Anella

Privacy Policy

Last updated: 10 August 2026

Anella is an offline ring sizer for iPhone. It is built to keep your information on your device. This policy explains, in plain language, exactly what data is and is not handled when you use Anella.

The short version Anella asks for no permissions at all — there is no camera, no location and no microphone in it. The sizes you save stay on your iPhone. The only information that leaves your device is the record of a purchase, so that your purchase works and can be restored — and even that is not tied to your identity.

What stays on your device

Your measurements. The measuring surface is the screen itself: you lay a ring on the display and match a circle to it. Nothing is photographed, scanned or recorded.
Saved sizes. Sizes you save, and the names you give them, are stored only in the app on your iPhone. They are not backed up to us, not shared, and not accessible to us.
Screen calibration. If you check Anella's accuracy against a bank card, what is stored is a single number describing your display — never an image of the card, and nothing about the card itself.

What is collected

Anella uses RevenueCat to manage its one-time purchase. When you buy Anella, or restore a previous purchase, the following is processed:

Purchase history — that a purchase was made, its product and status. This is used only to unlock the app you paid for, to restore it on your devices, and to understand aggregate sales. It is associated with an anonymous, app-generated identifier — not with your name, email, or Apple Account, and it is not used for advertising or cross-app tracking.

Payments themselves are handled entirely by Apple through the App Store. Anella never sees or receives your payment details.

What is never collected

No camera, photo library, location, microphone or motion access — Anella requests no permissions of any kind.
No account, name, email address, or phone number.
No advertising identifiers and no tracking across apps or websites.
No analytics SDKs beyond the purchase processing described above.

Service providers

Two providers act on our behalf: Apple (App Store payments and delivery) and RevenueCat (purchase management, described above). Each processes only what is needed for the purchase to function, under their own privacy terms.

Your rights

Because Anella holds no account and stores your sizes only on your device, deleting the app removes that data from your phone. For the anonymous purchase record held by our providers, or any question about your data — including access or deletion requests under the GDPR or similar laws — contact us at the address below and we will help.

Children

Anella is not directed at children and does not knowingly collect data from children.

Changes

If this policy changes, the updated version will be posted here with a new date.
