Sonor — Privacy Policy
The short version
Sonor keeps everything on your phone. We don’t have an account system, we don’t run a server that holds your data, and we don’t send your medication information anywhere. There is no advertising and no third-party analytics. Your data is yours — you can export it, and if you uninstall the app, it’s gone.
If any of that ever changes, we will update this policy before the change takes effect and ask for your explicit consent first.
What data Sonor handles
To do its job, Sonor stores information you enter and generate while using the app:
- Your prescriptions and treatments — names you give them, the prescribing doctor if you add one, start and end dates, and notes.
- Your medications — the medication name you type in, dose, schedule, relationship to meals, and start/end dates.
- Your intake records — when a dose was due, and whether you marked it taken, skipped, or postponed.
- Your inventory — how many units you have left and your refill reminder threshold.
- Your app settings — sleep window, chosen language, and alert preferences.
This is health data. Under the EU General Data Protection Regulation (GDPR), information about your health is a special category of personal data that deserves extra protection. We treat it that way. The most protective thing we can do — and the design choice at the heart of Sonor — is to never let it leave your device in the first place.
Where your data lives
All of the above is stored only on your device, in Sonor’s private app storage, inside a local database. It is not uploaded to us or to anyone else. It is not backed up to a cloud by Sonor.
Your data benefits from your device’s built-in encryption. Modern Android devices encrypt on-device storage by default (typically once you set a screen lock such as a PIN, pattern, password, or biometric). We strongly recommend you keep a screen lock enabled, because on this version of Sonor your phone’s own security is what protects your health data at rest.
What we do NOT do
We think the clearest way to describe a privacy-first app is to be explicit about what doesn’t happen:
- We do not transmit your data. Nothing you enter is sent off your device by Sonor.
- We do not have accounts or sign-in. We never ask for your name, email, or phone number to use the app.
- We do not sell or share your data. There is no one to sell it to — we don’t receive it.
- We do not show advertising. No ad networks, no ad identifiers, no tracking for ads.
- We do not run third-party analytics. We do not measure your behavior with tools like Google Analytics, Firebase Analytics, or advertising SDKs in this version.
- We do not use your data to train anything.
A note on crash reporting (transparency about the future): We may, in a future update, add crash-and-error reporting (for example, using Sentry) purely to find and fix bugs that break reminders. If we ever do, we will scrub those reports of any personal or health data before they are sent, we will describe it plainly in this policy, and — where it’s the appropriate legal basis — offer it as an opt-in. As of this version, no such reporting is integrated and nothing is sent.
Android permissions we request, and why
Sonor asks for a small set of permissions. Every one exists to make your reminders fire reliably — that is the whole point of the app. None of them is used to collect or transmit data.
- Notifications (
POST_NOTIFICATIONS) — to show your medication reminders. Without this, Sonor can’t alert you. - Alarms & reminders / exact alarms (
USE_EXACT_ALARM/SCHEDULE_EXACT_ALARM) — to fire a reminder at the exact minute a dose is due, instead of “sometime later” when Android is saving battery. For medication, the exact time genuinely matters. - Run at startup (
RECEIVE_BOOT_COMPLETED) — Android clears all scheduled alarms when you restart your phone. This lets Sonor quietly re-schedule your reminders after a reboot, so you don’t silently lose a day of alerts. - Full-screen alert (
USE_FULL_SCREEN_INTENT) — so a critical reminder can wake the screen and show over the lock screen if you haven’t responded, instead of sitting silently in the notification tray. - Keep the screen awake (
WAKE_LOCK) — to turn the screen on when an alarm fires. - Ignore battery optimization (
REQUEST_IGNORE_BATTERY_OPTIMIZATIONS) — to let you exempt Sonor from the battery-saving features that would otherwise put it to sleep and stop your alarms. This is a choice Sonor offers you; it never happens without your action. - Foreground service (
FOREGROUND_SERVICE) — to keep a critical alarm alive and audible even when Android would otherwise shut the app down.
You can review or change these anytime in your phone’s Settings. If you deny some of them, Sonor still works, but your reminders may become less reliable — we’ll tell you when that’s the case.
Exporting and deleting your data
- Export — Sonor lets you export your data (for example to CSV or JSON) so you can keep a copy, move to another tool, or share it with your doctor. Once you export a file, that copy is in your hands and under your responsibility — where you save it or send it is outside Sonor’s control, so treat it as the sensitive health information it is.
- Deletion — Because everything lives on your device, uninstalling Sonor deletes all of your Sonor data. There is no separate server copy to request the deletion of. You can also clear the app’s data from your phone’s Settings.
Children
Sonor is intended for adults managing their own medication, and for caregivers. It is not directed at children and we do not knowingly collect data from children. If a minor uses the app, that should happen under the supervision and consent of a parent or guardian. (In any case, Sonor does not transmit or collect data centrally in this version.)
Medical disclaimer
Sonor is a medication reminder and tracking tool. It is not a medical device and does not replace advice from a qualified healthcare professional. It does not diagnose, does not recommend treatments or doses, and does not check for drug interactions. For any question, consult your doctor or pharmacist. In an emergency, call your local emergency services.
Changes to this policy
If we update this policy, we’ll change the “Effective date” above and make the new version available at the same place. If a future version of Sonor ever adds features that change how data is handled — for example cloud sync or a caregiver mode that shares a patient’s data with a family member — we will update this policy before those features go live and obtain your explicit consent before any of your data leaves your device.
