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.
There is one exception, and it is the subscription. If you subscribe, purchase data is handled by Apple and by RevenueCat, our subscription provider. 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. None of it is sent to us or to anyone else, and we have no way to read it:
Deleting Whittle from your iPhone deletes all of it. There is no backup on our side to remove, because there was never a copy.
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 app receives usage figures inside a sandbox that cannot make network requests, and 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, and it does not block or restrict any app.
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, and only if you subscribe or restore a purchase.
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 at most one notification a week, and it is 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.
