Firuze Privacy Policy · Topkir Studio

Firuze is designed to work with as little data as possible. You don't need an account, there are no ads, no tools that track you across other apps and websites, and your data is never sold. This policy explains how the app uses information on your device and when it communicates with third-party services.

Data controller: Topkir Studio (Ahmet Topkir).

Summary

No account, no sign-up, no ads, no cross-app tracking.
Your location, preferences and worship progress stay on your device.
To improve the app, anonymous usage statistics and crash reports are collected with Google Firebase; they are not linked to your name or email.
Firebase Cloud Messaging is used for announcement notifications and RevenueCat for Premium purchases.
If you use the feedback form, the message you write (and your optional email) is sent to us.

Information processed on your device

Location. If you grant permission, your device's approximate location is used to calculate prayer times and determine your city. The calculation happens entirely on your device; your location is never sent to any server. You can pick your city from a list without granting location permission, and you can revoke the permission at any time in your device settings.

Preferences and progress. Your selected city, notification settings, dhikr counts, custom dhikr, Quran reading progress and favorites are stored in your device's local storage and are deleted when you delete the app.

Notifications. Adhan, prayer reminders, Friday and holy night reminders and the trial-ending reminder are scheduled locally on your device. Remotely sent notifications such as announcements use Firebase Cloud Messaging (see below).

Widgets. The prayer time and dhikr information shown by home screen widgets is kept in an on-device area shared between the app and its widgets (an App Group on iOS).

Focus (iOS only). This feature uses Apple's Screen Time (Family Controls) framework. The apps you choose to lock are provided by Apple as encrypted tokens; Firuze cannot see which apps you use and this information never leaves your device.

Third-party services

RevenueCat (subscription management). RevenueCat, Inc. is used to validate Premium purchases and check your subscription status. RevenueCat processes a randomly generated anonymous user ID, purchase records (product, date, price, store transaction ID), device/OS information, app version and IP address for country detection. Your name and email are not shared. Details: revenuecat.com/privacy.

Apple App Store / Google Play. Payments are processed by the stores; we never see your card details. The stores' own privacy policies apply.

Google Fonts. Some fonts are downloaded from Google's servers on first use and cached on your device. During this request your IP address is technically transmitted to Google; no other information is sent.

Google Firebase services

Firuze uses the following services of Google LLC's Firebase platform. Firebase uses a randomly generated identifier for each installation (Firebase installation ID / app instance ID); your advertising identifier (IDFA/AAID) is not accessed.

Google Analytics for Firebase (usage statistics). Which screens are opened and in-app events such as marking a prayer, completing dhikr, unlocking Focus, viewing the Premium screen and purchase steps; device model, operating system and app version, language, and approximate country/city derived from your IP address. The purpose is to understand how the app is used and improve it. This data is not used for advertising or ad personalization.
Firebase Crashlytics (crash reports). When the app crashes: technical details of the error, device model, operating system, app version, language and Premium status. The purpose is to find and fix bugs.
Firebase Cloud Messaging (push notifications). If you allow notifications, a notification token is created so we can send announcements to your device. The token is added to topic groups based on language, platform and Premium status.
Firebase Remote Config and In-App Messaging. Settings such as update prompts, screen text experiments (A/B tests) and special day dates, as well as in-app announcements, are fetched from the server. The installation ID, app version, language and country are used for this.
Cloud Firestore (feedback). If you use the “Send feedback” form in Settings, the category you choose, your message, the email address you optionally provide, app version, operating system and version, language and Premium status are stored. This information is only used to read your message and, if you wish, reply to you.

Retention

Analytics data is kept for up to 14 months according to Google Analytics retention settings and crash reports for 90 days. The notification token becomes invalid when you delete the app or don't use it for a long time. Feedback messages are kept for up to 2 years after the matter is resolved, or deleted on request.

International transfers

RevenueCat and Google (including Firebase) servers are located outside Turkey (mainly in the US and EU); feedback messages are stored on Firestore servers in the US. Data sent to these services is transferred only as necessary to provide the service and on the basis of contractual safeguards.

Children's privacy

Firuze is suitable for all ages and does not knowingly collect personal data from children. Premium purchases are subject to the stores' parental controls.

Deleting your data

Firuze has no accounts. Deleting the app removes all data from your device. If you want feedback you sent, the anonymous purchase record at RevenueCat or the anonymous usage data in Firebase deleted, contact us by email.

Under the EU General Data Protection Regulation (GDPR) and Turkey's Personal Data Protection Law No. 6698 (KVKK), you have the right to know whether your data is processed, to request information, to request correction or deletion, to object to processing, and to seek compensation for damages.

You can send your request to the email address below; we respond within 30 days at the latest. You also have the right to lodge a complaint with your local data protection authority (in Turkey, the Personal Data Protection Authority).

Changes

If this policy is updated, the new version will be published on this page and the date above will change. Material changes will be announced in the app.
