Privacy Policy
Effective October 15, 2026
The short version.restability has no accounts. The apps you choose to lock stay on your phone, and we can't see them. Your workouts and history live on your device and in your own iCloud. What reaches us is limited to usage analytics, crash reports, purchase status, and a few milestone events used to measure our ads, all tied to a random ID made on your phone, never to your name or email. We don't ask to track you across other apps, and we don't sell your data.
Who we are
restability ("we", "us") is a rest timer for iPhone and iPad that locks the apps you choose while you train and unlocks them while you rest. Questions about this policy: support@tryrestability.com.
What we don't collect
- No account.There's no sign-up. We never ask for your name, email address, phone number or password.
- No Screen Time data.You choose the apps to lock with Apple's Screen Time picker. Apple gives restability an opaque token for each one, not the app's name, and those tokens never leave your device. We can't see which apps you lock or how you use them.
- No advertising identifier.restability doesn't ask to track you across other companies' apps and websites, and doesn't read your device's advertising identifier (IDFA).
- No location, contacts, photos or health data.
What stays on your device and in your iCloud
Your saved workouts, rest settings, weekly goal, preferences and workout history are stored on your device. A workout's history includes its name, when it started and ended, its sets and rests and how long each one ran, and a few facts about the setup it ran on: the app and iOS version, the device model, the time zone, your plan, and whether Screen Time and notifications were on (counts and on/off states, never which apps).
If you're signed in to iCloud, restability syncs this to your own private iCloud storage so it follows you to your other devices and survives a reinstall. That storage belongs to your Apple Account, and we can't read it. Your locked apps never sync.
Notifications and the Lock Screen countdown are created on your device. They don't go through a server of ours.
The random ID
The first time restability opens, it makes a random ID (like "install-3f9a…") and keeps it on your device. It isn't linked to your name, email or Apple Account. It's how the services below tell one install apart from another. Delete the app and the ID goes with it; reinstalling makes a new one.
What leaves your device
1. Usage analytics (PostHog)
We use PostHog to learn how the app is used so we can improve it: screens viewed, features used, workouts started and finished, how rests compared with their plan, settings you change, the answers you give during setup (such as how you train and your usual rest), whether you allowed Screen Time and notifications, how many apps you locked (a count, not which ones), paywall views and purchase steps, and when the app is opened or closed. These events carry the random ID and basic device information, such as the device model, iOS version, app version, language and time zone. They never include your workout names or anything you type.
2. Crash reports (Sentry)
When something goes wrong, Sentry receives a technical report, such as the error, what the app was doing just before it, the device model, iOS version and app version, and the random ID, so we can find and fix the problem. We use crash reports only to fix bugs.
3. Purchases (Apple and RevenueCat)
Purchases are made through Apple. We use RevenueCat to check what you've bought and whether a subscription or trial is active, identified by the random ID. RevenueCat receives the purchase records Apple provides. Neither we nor RevenueCat ever see your payment details.
4. Measuring our ads (Meta)
We advertise on Meta's platforms (Facebook and Instagram) and need to know which ads bring people to restability. The app includes Meta's SDK, which records that the app was installed and opened. We also send Meta a few milestones: finishing setup, allowing Screen Time, finishing your first workout, starting a free trial, and making a purchase (with its price and currency). These are tied to the random ID, and Meta also receives basic device information, such as the device model, iOS version and IP address, as part of how its SDK works.
Meta does not receive your workouts, your history, your locked apps or anything you type. Because restability doesn't ask to track you, Meta doesn't get your device's advertising identifier from us. Meta handles what it receives under its own privacy policy.
5. When you email us
If you write to support@tryrestability.com, we receive your email address and whatever you send, and use them only to reply and help.
Who we share data with
Only the services named above, each acting for us: PostHog (analytics), Sentry (crash reports), RevenueCat (purchases), Meta (ad measurement) and Apple (the App Store and iCloud). We don't sell your personal information, and we don't share it with anyone else unless the law requires it.
Keeping and deleting your data
- Erase All Datain restability's Settings deletes your workouts, history and settings on this device and in your iCloud, so your other devices clear too.
- Deleting the app removes everything stored on your device, including the random ID.
- You can also remove restability's iCloud data in the Settings app: tap your name, then iCloud, then Manage Account Storage.
- Analytics, crash reports and purchase records are kept by those services for a limited time. To ask us to delete what's tied to your install, or to see it, email support@tryrestability.com. Because we don't know who you are, we may ask you for details from the app to find your records.
Your choices and rights
Depending on where you live, you may have the right to access, correct, delete or move your personal data, and to object to how it's used. Email support@tryrestability.comand we'll help. You can also turn off iCloud for restability, or Screen Time and notifications, at any time in the Settings app.
Children
restability isn't directed at children under 13, and we don't knowingly collect personal information from them.
Changes
If this policy changes in a meaningful way, we'll update this page and the effective date at the top.
