Whittle has no accounts, no sign-in, no advertising and no analytics. The screen-time figures the app is built around are read on your iPhone, stored on your iPhone, and never transmitted anywhere by the app.
There is one exception, and it is the subscription. Every copy of Whittle, subscribed or not, asks RevenueCat, our subscription provider, whether a subscription is active; if you subscribe, the purchase itself is handled by Apple and RevenueCat. That is the whole of it, and the rest of this page explains it precisely.
Whittle is an iOS app published by Mustafa Emir (“we”, “us”), an individual developer based in Türkiye. Under Turkish law (KVKK, Law No. 6698) we are the data controller for the limited processing described below. This policy covers the Whittle app and nothing else. Contact details are at the bottom of the page.
All of the following is stored locally on your device, in the app’s own storage. The app sends none of it to us or to anyone else, and we have no way to read it:
The Home Screen widget reads its figure from the same storage on your iPhone. Deleting Whittle from your iPhone deletes all of it. There is no backup on our side to remove, because there was never a copy.
One thing only you can send: Share diagnostics in Settings puts together a plain-text report — the app and iOS versions, the state of the measurement and the program, and the last two weeks of daily totals, with no app names and no app tokens — and hands it to the iOS share sheet. It goes only where you choose to send it, and only if you do.
Whittle uses Apple’s Family Controls and Device Activity frameworks to measure how long you spend in the apps you chose. Apple designed these frameworks so that the data stays on the device. The minutes are counted by a Screen Time extension on your iPhone and kept in the app’s own storage there; the app sends none of them anywhere, apart from the diagnostics report above, which only goes where you send it. The app identifiers it receives are opaque tokens with no readable name attached.
Whittle asks for this access for your own device only — the individual authorization, never the parent-or-guardian one. It does not monitor anybody else.
With Whittle Pro, the app also uses Apple’s Managed Settings framework: once the day’s minutes are used, a pause appears in front of the apps you chose, and Open anyway lifts it. That happens on your iPhone, from the same opaque tokens. While a pause is up, iOS may hold back notifications from those apps; Whittle never sees or receives those notifications.
Apple’s Screen Time API reports duration only. It does not report, and we cannot see, what you looked at, who you spoke to, or anything you typed.
Only subscription data. Every copy of Whittle, subscribed or not, checks the subscription status with RevenueCat when it starts, when it comes back to the foreground, when the paywall loads prices, and when you buy or restore.
Apple. The purchase itself is made through the App Store. Apple processes the payment and we never see your card details, your Apple Account email, or your name. Apple’s handling of that transaction is governed by Apple’s Privacy Policy.
RevenueCat. We use RevenueCat, Inc. to tell the app whether your subscription is active and to restore it on a new device. When the app starts, RevenueCat generates a random, anonymous identifier for the installation. We do not create accounts and we do not attach your name, email, or any other identity to that identifier. RevenueCat receives:
This is used for one thing: knowing whether to unlock the paid features. It is not used for advertising, not combined with data from other apps, and not sold. RevenueCat’s own policy is at revenuecat.com/privacy.
For clarity, this is exactly what we have declared to Apple:
| Data type | Purpose | Linked to you | Tracks you |
|---|---|---|---|
| Purchase History | App Functionality | No | No |
| Device ID | App Functionality | No | No |
| User ID | App Functionality | No | No |
Your screen-time data does not appear in that table because it is never collected in Apple’s sense of the word — it does not leave the device.
Whittle sends one notification when your first number is ready, and after that at most one each Sunday: with Whittle Pro, this week’s and next week’s targets; without it, the daily average of the past seven days, sent only when every one of those days was counted. Both are scheduled and delivered by your iPhone itself. There is no push server and no push token: we could not send you a message if we wanted to. You can turn notifications off inside the app or in iOS Settings.
On your device: for as long as the app is installed. At RevenueCat: for as long as the subscription record is needed to keep your purchase restorable, and in line with their retention practices. Because the record is anonymous, deleting the app and losing the identifier means the record can no longer be connected to you at all.
If you are in the European Economic Area, the United Kingdom, Türkiye, or a jurisdiction with comparable law, you have the right to access, correct, delete, and port your personal data, and to object to or restrict its processing. In California, you have the right to know what is collected, to delete it, and not to be discriminated against for exercising those rights.
In practice, most of that is already in your hands: the screen-time data is on your device and deleting the app erases it. For the subscription record held by RevenueCat, write to us at the address below and we will act on the request within 30 days. Please note that we may need the App Store receipt or order ID to find an anonymous record, since there is no account to look you up by.
Our legal basis for processing subscription data is the performance of the contract you enter into when you subscribe. There is no processing based on consent, because there is nothing else being processed.
RevenueCat and Apple operate internationally, so subscription data may be processed in the United States and elsewhere. Both rely on the standard contractual clauses or equivalent safeguards for transfers out of the European Economic Area and the United Kingdom.
Whittle is not directed at children under 13, and we do not knowingly collect personal information from them. The app requests Screen Time access for the person using the device, not for a child being supervised by someone else.
If the app’s data practices change, this page changes with them and the date at the top is updated. Material changes will also be reflected in the App Store privacy label before the version that causes them is released.
