Krezzi Apps Privacy Policy
Last updated: 06 July 2026
Who we are
Krezzi Apps (“Krezzi Apps”, “us”, “our” or “we”) provides this Privacy Policy to describe how we handle information in connection with the Krezzi Apps website at https://krezziapps.com and the mobile apps we develop and operate (each a “Service”). Krezzi Apps is a sole proprietorship (eenmanszaak) registered in the Netherlands.
Our approach
All Krezzi Apps are built privacy-first: we do not require user accounts, we do not operate our own servers for user data, and everything you create in our apps (such as workouts, settings, or progress) is stored locally on your device. We ourselves do not collect, store, or process personal data on our own systems. Where a specific app uses a third-party service (such as advertising) or a device feature (such as Apple Health), this is described in the app-specific sections below.
Apps with advertising
This section applies to: “Sienna: Interval Timer”
These apps are free to use and display advertising provided by Google AdMob, a service of Google Ireland Ltd. / Google LLC. To provide and improve ads, Google may collect and process data from your device, including device identifiers (such as the Apple advertising identifier, IDFA), IP address, approximate location derived from it, and interactions with ads. We do not receive or store this data ourselves.
Consent. In the European Economic Area and the UK, we ask for your consent before any advertising data is processed, using Google’s consent management platform when you first launch the app. On iOS, Apple’s App Tracking Transparency prompt additionally controls access to the advertising identifier. If you decline, you may see non-personalized ads, which rely on contextual information rather than your profile.
Withdrawing consent. You can review or withdraw your advertising consent at any time inside the app under Settings → Privacy options. You can also change tracking permission in iOS Settings → Privacy & Security → Tracking.
Removing ads. These apps offer a one-time in-app purchase that permanently removes all advertising. After this purchase, no ad requests are made and no advertising data is processed.
For details on how Google processes data, see Google’s privacy policy at https://policies.google.com/privacy and https://business.safety.google/adsservices/.
Health and fitness data
This section applies to: “Sienna: Interval Timer”
On Apple Watch, the app can record workout sessions, including heart rate and active energy burned, and save completed workouts to Apple Health. This data is processed on your device and stored in Apple Health under your control. It is never transmitted to us or to any third party by our apps, and it is never used for advertising or any other purpose. You can manage or revoke Health access at any time in the Health app or in Settings → Privacy & Security → Health, and you can delete recorded workouts in Apple Health at any time.
Data stored on your device
Content you create in our apps — such as workout templates, workout history, notes, and app settings — is stored locally on your device only. It is deleted when you delete the app. Reminders and timer alerts use local notifications generated on your device; no notification data leaves your device.
Children’s Apps
This section applies to: “PuzzlePark”
Our children’s apps do not collect, store, or process any personal data. They do not show advertising, do not use analytics, cookies, or tracking tools, and do not share any data with third parties. They are designed to work fully without access to your or your child’s personal information, in line with the GDPR and children’s privacy principles. Since no personal data is collected or processed, no parental consent is required.
In-app purchases
Our apps may offer optional in-app purchases through the Apple App Store. These transactions are processed entirely by Apple. We do not have access to, and do not store, any personal or payment information.
Your Rights
Under the GDPR you have the right to access, correct, delete, and restrict the processing of your personal data, the right to data portability, and the right to withdraw consent at any time. Since we do not process personal data on our own systems, requests regarding advertising data are best addressed by withdrawing consent in the app (see above) or directed to Google as the processing party. You also have the right to lodge a complaint with your supervisory authority; in the Netherlands, this is the Autoriteit Persoonsgegevens.
Language and Legal Validity
This Privacy Policy is provided in English. If translations are offered for convenience, the English version shall be legally binding.
Changes to This Policy
If our data practices change — for example, if a future app uses additional services — we will update this Privacy Policy accordingly and note the date of the last revision above.
