Priozar
Privacy Policy
Last updated: 8 September 2026
The short version
Priozar runs on your phone. The apps you choose to be interrupted for, and when you open them, never leave your device — not to Priozar, not to anyone else. If you turn on the optional account, your priority titles and your focus-session history sync so you can pick up on a second device; nothing else does. If you buy Pro, the purchase goes through Apple or Google — we never see your payment details.
The rest of this page explains that in full, because “trust us” isn’t good enough for an app that watches which apps you open.
What Priozar does on your device
Priozar’s core purpose is helping you notice a distraction and choose what to do about it. To do that, it needs to know when you open an app you’ve asked it to watch for. That detection happens entirely on your device:
- Android: Priozar reads the name and timestamp of the app currently in front, using Android’s Usage Access permission, which you grant and can revoke at any time in Settings. It compares that against the list of apps you chose, on the device, and nothing about what it observed is sent anywhere.
- iOS: Priozar uses Apple’s Screen Time API (Family Controls) to shield the apps you choose. Apple’s system tells Priozar that a shielded app was opened — it does not tell Priozar, and Priozar never asks, which specific app or website it was. That distinction is built into the operating system, not into our promise.
Priozar never reads screen contents, message contents, keystrokes, notification contents, your browsing history, microphone, or camera — on either platform, whether or not you’ve granted the permissions above.
Screen time on the Progress screen (Android only)
Priozar’s Progress screen can chart how much time you spend in the apps you chose to be interrupted for. On Android, that comes from the same Usage Access permission described above. It is worth being precise about what this does and does not involve:
- Android tells Priozar how long each app was in the foreground. Priozar adds those numbers up on your device into two totals per day — time in the apps you chose, and time in all apps — and keeps only those totals. The per-app breakdown is discarded where it is calculated and never reaches the rest of the app.
- Priozar excludes itself from both totals. Time spent reading your own progress is not screen time it should take credit for.
- None of it is ever sent anywhere. There is no column for it in our database, and it is not part of what syncs when you have an account.
- On iOS this chart is simply absent. Apple’s Screen Time system never tells an app how long anything was used, and Priozar does not ask.
What syncs, if you choose to create an account
An account is entirely optional. Priozar’s core loop — detection, intervention, focus timers, progress — works fully offline, with no account at all. Creating one buys exactly two things: carrying your data to a second device, and (if you buy Pro) carrying that purchase between Android and iOS.
If you do create an account and turn on sync, this is sent to our server (hosted on Supabase) and stored against your account:
| What syncs | What it looks like |
|---|---|
| Your email address | Used only to sign you in. |
| Onboarding answers | Whether you’re a student or professional, your communication-tone preference, your control-strength setting. Fixed choices, not free text. |
| The goal categories you picked | A catalogue key like “work-career” — not anything you typed. |
| Your priority titles | Whatever you type when you add a priority. This is the one place your own words are stored on our server, and it’s there so you can see your list on a second device. |
| Focus-session history | When a session started and ended, how long it was, whether it came from an interruption or was started manually. |
| A small event log | What happened and when (an intervention was shown, a session completed, an allowance was granted) — never which app it was about. |
What never syncs, even with an account and sync turned on: the Android package names or iOS app selections you’ve chosen to be interrupted for. There is no column for them in our database — this isn’t a setting you could accidentally change, it’s how the server is built. The list is not stored and then protected; there is nowhere on the server to put it, so there is nothing to leak, hand over, or misconfigure.
If you sign out or never sign in, none of the above ever leaves your device.
Purchases
If you buy Priozar Pro, the purchase is handled entirely by the Apple App Store or Google Play. We receive confirmation of what plan you’re entitled to — we do not receive your card details, billing address, or any other payment information; Apple and Google never share that with us. Restoring a purchase (if you reinstall, or move to a new phone on the same platform) is handled by the store directly.
Your export and deletion rights
From the Account screen, you can export everything Priozar holds about you as a single file, at any time, with no account required. That export deliberately includes the apps you’ve chosen to intercept, even though that list never leaves your device otherwise — it’s your data, and a copy that quietly left something out would be dishonest. What you do with the file afterwards — store it, delete it, share it — is your decision, and the export says so.
If you have an account, deleting it removes your account and everything synced with it from our server, permanently. Your on-device data (priorities, blocking rules, progress) is untouched — deleting your account signs you out of sync, it does not reset the app on your phone. How to delete your account sets out the steps, and exactly what is removed and what is kept.
Crash reports
Priozar does not use a third-party crash-reporting service. If the app crashes, the only report generated is the one your phone’s own operating system collects (Android vitals via Google Play, or — only if you’ve opted in to sharing analytics with app developers — crash reports via Apple). Neither requires anything from Priozar beyond existing as an installed app; neither is something we can turn off or configure, and neither sends us your name or any of your data — just that a crash happened, on what OS version, and where in the code.
Advertising and tracking
Priozar shows no ads, and contains no advertising or tracking SDK. There is no cross-app or cross-site tracking of any kind. This website sets no cookies and loads no third-party resources.
Changes to this policy
If this policy changes in a way that affects what Priozar collects or how it’s used, we’ll update this page and the date above it. We won’t quietly widen what’s collected without saying so here first.
