Privacy policy
Effective October 29, 2026 · Last updated October 30, 2026
The short version. Parent Radar works on your iPhone. Your school logins are kept on your phone, and your kids' grades and your calendars are read there. Parent Radar never reads your email. If you choose Google for your kids' calendars, it asks Google for one narrow permission: to make those calendars and manage the events on them. It cannot see your other calendars or anything else in your Google account. Two things leave your phone and pass through our server without being stored: the daily texts, which can name grades, assignments and calendar events, on their way to your family's phones, and the words of school posts, on their way to be read for dates. Our server keeps the phone numbers your family's texts go to and the consent for each, plus random IDs with no names. We do not sell data, show ads, or use your family's information to train AI.
Who we are
Parent Radar is made by Plumworth LLC, an Illinois company, 948 Crescent Boulevard, Glen Ellyn, IL 60137. Contact us at hello@plumworth.com. Parent Radar is for parents and guardians in the United States. Using it also means agreeing to our terms of use.
What Parent Radar handles, and where it stays
| Information | Why | Where it is kept |
|---|---|---|
| Your school gradebook sign-in | To check grades and missing work | Only in your iPhone's Keychain. Never sent to us. |
| Grades, assignments, missing work | To write the daily texts | Read and kept on your iPhone. The lines a text includes, such as a grade, an assignment that is due or missing, leave your phone inside that text, as set out under "The words of each text" below. |
| Your ParentSquare sign-in | To read school posts and teacher messages | Only on your iPhone, in the app's own private sign-in storage, kept out of backups. Never sent to us. |
| ParentSquare posts and teacher messages | To find dates, early dismissals and to-dos | Kept on your iPhone. To pull out dates, each post's sender name, date, subject and words pass through our relay, without being stored, to Anthropic's Claude AI, which does not use them for training. Our relay takes out phone numbers and email addresses written in the usual formats first, and changes nothing else. Other details in a post, including classmates' names, can still reach Anthropic. |
| Your kids' grade levels, and your school's name and calendar note if you enter them | To sort school posts by kid | On your iPhone. Sent with the posts to Anthropic, as above, with each kid known only by a random code. Your kids' names are not sent, though a post itself may mention one. |
| Calendars on your iPhone, such as your kids' and teams' calendars | To include practices, games and events | Read on your iPhone. An event's title and time leave your phone inside a daily text, as set out under "The words of each text" below. |
| Your kids' calendars, your school's public calendar, and team calendar links you paste | To put school dates and team events on each kid's calendar | Parent Radar makes one calendar for each kid, named like "Maron stuff", on your iPhone (iCloud) or in your Google account, whichever you choose, and adds that kid's school dates and team events to it. On your iPhone it reads your family's calendars only so it never adds the same date twice. It fetches your school's public calendar from the district's website, and each team calendar link you paste from the team's own site. If you choose Google, the dates go from your iPhone straight to Google Calendar, never through our server, and Google keeps them like any of your calendars. If you type someone's email to share a kid's calendar, Google lets that person see it and may email them. Each date it adds is marked "Added by Parent Radar", and it only ever changes or removes dates it added. |
| Kids' first names, history of texts sent | To address and not repeat texts | On your iPhone. A text can include a kid's first name. |
| Phone numbers of family members who get texts, and the parent's consent | To deliver the texts | On our server, with a random family ID and no names. For each number we also keep the date and time of the consent and which parent gave it, when the welcome text went out, when the number replied JOIN, and the date and time of any STOP or START reply. |
| A one-time code texted to the parent setting up Parent Radar | To confirm that parent's number is theirs | On our server in scrambled form only, and deleted 10 minutes after it is sent, used or not |
| A record of each consent, JOIN, STOP, START and removal | To prove we only text people who agreed | On our server, with the phone number and family scrambled with a secret key we keep, so they can't be read without that key, the date and time, and the version of this policy. Kept 4 years after the number is removed or the family deleted, as set out below. |
| A scrambled code of each number your family has ever added, with when it was sent the JOIN text | So your family sends a number that text only once, even if it is removed and added again, and to count the limit of 8 numbers | On our server, scrambled with the same key, until your family is deleted |
| A scrambled code of a number and each time it was sent a JOIN text | So no number gets that text more than once a day or 3 times in 30 days, from all families together | On our server, scrambled with the same key, for 30 days |
| Your family's time zone | To send texts at the right local times | On our server |
| A random code for each kid, made on your iPhone | To send each kid's text to the right group | On our server. It is not the kid's name and cannot be turned back into one. |
| Notices waiting for 8 a.m., a code waiting to be used, and counts of recent texts and requests | To keep our own texts to daytime hours and limit how many go out | On our server. Deleted with your family; counts of requests are kept for 2 days. |
| The time your app last checked in, how many weekday checks in a row it missed, and a secret key your app uses to sign its requests | To tell parents if a daily check did not run, and to make sure only your app can send your family's texts | On our server. The key is stored encrypted. |
| The words of each text | To deliver it | A text can include grades, assignments that are due or missing, school dates and the titles and times of calendar events. It passes through our server and our text-message provider, Twilio, on the way to your family's own numbers. We do not store it, and Twilio's copy is deleted after delivery. |
| Replies to our texts | To honor STOP, START, JOIN and HELP | STOP, START, JOIN and HELP, and the other STOP words below, are the keywords. We act only on a reply that is one of those keywords. Every other reply is discarded: our server does not keep it, and deletes Twilio's copy right away. In a group text, your reply also reaches the others in the group, as with any group text. |
| Emails you send us | To answer you and help with setup | In our email inbox, only as long as we need it to help you |
| A calendar makeover request | To help you set up your calendar | The makeover request is an email you send us yourself, with the calendar account types and answers you chose. A person at Plumworth reads it and, if you go ahead, helps you reorganize your calendar with your permission. Nothing gets deleted without your OK. It is kept like other emails you send us. |
| A family member's device you add, such as your kid's or the other parent's iPhone | To show that person their part of Parent Radar | If you add a family member's device, your phone sends that device only the kids you chose, sealed with a key only the two devices have, through Apple's iCloud. Apple stores only the sealed copy, along with a random record name and when it was made and last changed, and cannot read the copy, and neither can we. A kid's device never gets another kid's information or anything meant for parents only. The device you add never signs in to anything and sends nothing back. Removing it stops all updates to that device and deletes the shared copy from iCloud at your phone's next check (right away if your phone is online). The removed device clears what it holds the next time it opens online. |
We collect this information from you, the parent, through the app and by email. We do not buy information about you from anyone, and we do not ask your kids for anything. The only things we act on from a kid are a STOP, START, JOIN or HELP reply.
Google Calendar. If you choose Google in Setup, Parent Radar asks for one permission: to make calendars and manage the events on the calendars it made (Google's "calendar.app.created" permission). It cannot read, change or delete any other calendar or anything else in your Google account. Its Google sign-in is kept in your iPhone's Keychain, and nothing from Google reaches our server. Parent Radar's use of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements. You can remove its access any time in your Google account's security settings, and Delete my family removes the sign-in from your iPhone.
Children
Parent Radar is used by parents. A parent installs the app, sets it up, and gives consent for each child's phone number to receive texts. Children do not create accounts and do not give us information. The only information about a child on our server is a phone number linked to a random ID and its consent record, kept so the parent's chosen texts can be delivered, plus the scrambled records described under "How long we keep things".
A kid sees Parent Radar on their own device only after a parent adds that device with a code from the parent's phone. The app on the kid's device has no account and no sign-in, collects nothing, and sends nothing to us or anyone.
We follow the Children's Online Privacy Protection Act (COPPA) for every child, whatever their age:
- Consent, one number at a time. Before a child's number gets any text, the parent or guardian who set up Parent Radar, whose own number we have confirmed with a code, confirms in the app that they are that child's parent or guardian and agrees to the texts. We record when that consent was given. Without it, the number gets nothing. Then the number itself gets one text asking it to reply JOIN, and gets nothing else until it does.
- What we handle about a child. On your iPhone: the child's first name, grades, assignments, school posts and the texts sent. On our server: the child's phone number, a random code, the consent record, and the scrambled records described below. If you add a family device, a sealed copy of that child's part in Parent Radar's iCloud space (which Apple and we cannot read) and on the device you added. Two things pass through our server without being kept: the words of each text, which can include the child's first name, grades and assignments, on their way to your family's phones; and the words of school posts, which can mention a child, on their way to be read for dates.
- What we never do with it. We never sell it, never use it for ads, never build a profile of a child, and never use it to train AI.
- Your rights as a parent. You can ask to see what we hold about your child, ask us to delete it, and tell us to stop collecting it at any time. In the app, Remove this number or Delete my family deletes it right away. Or email hello@plumworth.com or write to the address above. We confirm you are the parent before we share or delete anything, and we answer within 7 days. Deleting a child's number stops that child's texts.
- How long we keep it. Only while your family uses Parent Radar, as set out in "How long we keep things" below.
School records and student privacy laws
Parent Radar is not a school service. Schools and districts do not use it, pay for it, or send it student records. A parent signs in with their own login to see their own child's records, which the parent already has a right to see. Federal school records law (FERPA) governs what schools share; it does not make Parent Radar part of the school.
Illinois's Student Online Personal Protection Act (SOPPA, 105 ILCS 85) and similar student privacy laws in other states cover services designed and marketed to schools. Parent Radar is designed and marketed to parents, so we do not believe those laws apply to it. We follow their main rules anyway, for any information about a student:
- We do not sell or rent it.
- We do not use it for targeted ads.
- We do not build a profile of a student for any purpose beyond the texts you asked for.
- We share it only with the service providers named below, for the purposes named below.
- We protect it with reasonable security and delete it when you ask.
Text messages
Texts go only to numbers a parent adds and consents for, and only after that number replies JOIN to the one text asking it to. A number that has not replied JOIN within 7 days of being added is removed, even if its JOIN text was still waiting to go out. Your family sends a number that text only once, even if it is removed and added again. A number gets that text at most once a day and 3 times in 30 days from all families together; one over that waits and goes out when allowed, unless the 7 days below run out first. If more than one family is waiting for the same number, the reply must be JOIN and the code from that family's text, such as "JOIN K7Q"; a plain JOIN then gets one text listing the choices by those codes only. A family can still add a number that replied STOP, but it gets nothing from Parent Radar until it replies START; then it gets that family's JOIN request. Notes meant only for parents go to a separate text with just the parents, never to a kid. Anyone who replies STOP gets no more texts from that moment. A text to Parent Radar's number that starts with STOP, END, QUIT, CANCEL or UNSUBSCRIBE, such as "Stop texting me", counts as STOP. In a group text, only a reply that is just one of those words, such as "Stop" or "STOP!", counts. START and JOIN count only as the whole reply, such as "Start" or "JOIN K7Q", so "Start the car" does not. Reply START to begin again. If a number replies STOP, we keep a scrambled code made from that number, not the number itself, even after your family's information is deleted, so we never text it again unless it replies START. That code is made with a key we never change, so it keeps working.
- Program: Parent Radar texts, from Plumworth LLC, sent from (630) 812-7996.
- How often: Up to 4 texts a day per child on school days (a morning and evening text to your child's group, and a morning and evening note to parents only), plus an occasional notice. Parents may also get one text on a weekday when the app could not check. After 3 weekdays in a row with no check, those texts stop until the app checks in again. Fewer on breaks and weekends. Texts from Parent Radar itself, such as codes, notices and the JOIN request, go out only between 8 a.m. and 8 p.m. your time. To a number that has not replied JOIN, they and the replies confirming JOIN and START also wait until it is between 8 a.m. and 8 p.m. where that number's area code is. Replies to STOP and HELP go out right away.
- Message and data rates may apply. Reply HELP for help. Reply STOP to stop.
- Consent to texts is not a condition of any purchase.
- We do not share phone numbers or text consent with anyone for their own marketing.
The full text message terms are in our terms of use.
Sharing
We do not sell or rent information. We use a text-message provider to deliver texts and a hosting provider to run our relay server; they handle phone numbers and message delivery only on our behalf. School posts from ParentSquare pass through our relay, without being stored, to Anthropic's Claude AI to pull out dates, with phone numbers and email addresses written in the usual formats taken out first; Anthropic does not use them to train its models. We disclose information if the law requires it.
These are the companies that help us run Parent Radar, and what each one gets:
| Company | What it does for us | What it receives |
|---|---|---|
| Twilio | Sends the texts | Family phone numbers, the words of each text (which can include grades, assignments and calendar events), and replies such as STOP, START and JOIN. Our relay deletes Twilio's copy of each text once it is delivered. Twilio may keep basic delivery records under its own rules for billing and phone carriers. |
| Fly.io | Hosts our relay server | Everything our server keeps, listed above, on an encrypted disk in the United States, plus the internet address of your phone when the app connects |
| Cloudflare | Serves these web pages | The usual details of a page visit, such as your internet address and browser type |
| Anthropic | Reads school posts to pull out dates | Each ParentSquare post's sender name, date, subject and words, with phone numbers and email addresses written in the usual formats taken out, plus your kids' grade levels under random codes and your school's name and calendar note if you entered them. No kid names, family IDs or phone numbers of yours, though a post's words can name your kids or other students. Anthropic does not train on them and may keep them only for a limited time under its commercial terms, for safety checks. |
| Apple | Delivers the app through TestFlight and the App Store | What Apple collects under its own policy when you install the app. Apple may share with us basic tester details, plus crash reports and feedback if you choose to send them. |
| Apple iCloud | Carries updates to family devices you add | Sealed copies only, which Apple and we cannot read, stored in Parent Radar's iCloud space and replaced at every check |
Each of these companies may use this information only to provide its service to us. If Plumworth is ever merged or sold, your information would move only under this policy, and we would tell you first.
How long we keep things
| Information | How long |
|---|---|
| Everything on your iPhone | Until you tap Delete my family or delete the app |
| Sealed copies for family devices | Replaced at every check. Deleted when you remove the device or tap Delete my family. |
| Phone numbers, consent records, random IDs and check-in times on our server | While your family uses Parent Radar. Deleted within 7 days, including backups, after you ask or after you leave Parent Radar. If your app has not checked in for 90 days, we treat that as leaving. |
| A number that never replied JOIN | Removed 7 days after it was added, whether or not its JOIN text has gone out yet. |
| The one-time code for the parent setting up Parent Radar | Deleted 10 minutes after it is sent |
| Scrambled code of each number your family has ever added | Until your family is deleted |
| Scrambled code of a number that was sent a JOIN text, and when | 30 days |
| Scrambled code for a number that replied STOP | Until that number replies START |
| Scrambled record of each consent, JOIN, STOP, START and removal (no phone number, no names) | 4 years after the number is removed or your family is deleted, as proof that we only texted people who agreed. Then deleted. |
| The words of texts and school posts | Not kept by us. Twilio's copy of a text is deleted after delivery. |
| Server logs | Up to 30 days, which is how our server is set up: it keeps no log files of its own, and no log copy is kept longer. They never contain message words, and show only the last two digits of a phone number. |
| Emails you send us | As long as we need them to help you, and deleted when you ask |
Deleting your information
In the app, Delete my family deletes your family's phone numbers, consent records and random IDs from our server right away, and from our server's backups within 7 days, and erases everything the app kept on your iPhone. If our server does not confirm the delete, because it can't be reached or does not accept the request, the app still erases everything on your iPhone and keeps asking our server to delete your family's records until it confirms. Remove this number deletes one number, though a scrambled code of it stays with your family's records, as set out above. The scrambled records in "How long we keep things" stay for the time set out there. Deleting the app also deletes what it kept on your iPhone; sign-ins that iPhone keeps in its Keychain after an app is deleted are erased the first time the app is opened again. If you delete the app and install it again, the new app deletes your family's records from our server the first time it is opened, and setting up again needs a new invite. You can also email hello@plumworth.com to delete your family's phone numbers from our server, and we will delete them within 7 days, including backups.
Your state privacy rights
Some states, including California, give people rights over their personal information. Whether or not those laws apply to a company our size, we give these rights to every family:
- Know: ask what we hold about you, where it came from, why we have it and who we share it with. The tables above answer this, and we will send you your own records on request. In the app, Export my family's records gives you everything our server holds about your family: your time zone, phone numbers and consent records, JOIN, STOP and START times, the scrambled consent records, every number your family has added, notices and replies waiting to be sent, a code waiting to be used, missed checks, and the counts we keep of texts and requests, alongside what the app keeps.
- Delete: ask us to delete it.
- Correct: ask us to fix a wrong phone number or record.
- Opt out: we do not sell personal information or share it for ads that follow you across other apps and sites, and we never have. There is nothing to opt out of, and we treat browser opt-out signals, such as Global Privacy Control, as a request anyway.
- Children's and sensitive information: we handle information about children only with a parent's consent, and only to send the texts the parent chose.
In the terms these laws use, we hold identifiers (phone numbers, random IDs, and your email address if you write to us). Education information (grades and assignments) is kept on your iPhone, and the lines of it a text includes pass through our server without being stored. Our sources are you and the school sites you sign in to on your phone. Our purposes are the ones in the tables above.
To use any of these rights, email hello@plumworth.com from the address you use with us, or write to the address above. You can also ask someone to act for you, with your written permission. We confirm the request comes from you, then answer within 45 days, and usually much sooner. If we say no, we will tell you why and how to appeal, and you can appeal by replying to that email. We will never charge you more, give you less, or treat you differently for using these rights.
Security
Your school sign-in is stored in the iPhone Keychain. Information between the app and our server is encrypted in transit. Our server is designed to hold as little as possible, so there is little to expose.
Every request from the app to our server is signed with a secret key only your app has, and that key is stored encrypted on our server. Kids are known to our server only by random codes. Only signed requests from your family's app can act on your family's information. If that key is ever exposed, we delete your family's records on our server at once, and you set up Parent Radar again in the app. Our service providers protect what they handle under their own security programs.
If something goes wrong
If someone gets into information we hold without permission, we will tell the affected families by email or text without undue delay, and within any time the law requires. We will say what happened, what information was involved, including any information about children, and what we are doing about it. We will also tell government authorities when the law requires it.
Early access list
If you sign up for early access on our website, we keep the email address, name and kids' schools and grades you type in, only to tell you when Parent Radar is ready for you. We don't sell or share the list, and we delete your entry when you ask at hello@myparentradar.com.
This website
These pages set no cookies and load no analytics, ads or tracking tools. Cloudflare, which serves them, keeps standard visit logs and may use a security cookie to block attacks.
Changes
If this policy changes, we will update the date above and tell beta families by text before the change takes effect. If a change would let us use information already collected in a new way, we will ask for your consent first.
