Version 2.6 · Last updated 6 November 2026

Privacy Policy
- 01
Who we are
Fun Math: Color Calculator (version 2.6) is published by denix.studio, founded by Gökhan Alp Atar, Nilüfer / Bursa, Turkey. This policy describes this app specifically — our other apps handle data differently and each has its own policy.
- 02
How Fun Math: Color Calculator handles data
Fun Math is built for the Kids category: it works offline, has no account and no analytics profile, and collects no personal data. Its App Store privacy label is “Data Not Collected”.
- 03
What is collected
Fun Math: Color Calculator may hold nothing personal — no name, no email, no contacts, no location and no advertising identifier; and only local settings such as sound, theme and chosen mascot.
- 04
Why
Data is used only to make Fun Math: Color Calculator work as described on its App Store page, to fix crashes and to keep the app secure. It is never sold, rented, or used to build an advertising profile.
- 05
Permissions this app asks for
Fun Math: Color Calculator asks for no system permissions: no location, no camera, no photo library, no contacts, no microphone.
- 06
Third parties
Fun Math: Color Calculator uses no advertising networks, no third-party analytics SDKs and no external processors. Nothing is shared with anyone.
- 07
Retention and deletion
There is nothing about your child held by us to retain, export or delete. Local settings disappear with the app.
- 08
Security
Data held on the device is protected by iOS app sandboxing and file-level encryption. Where information does travel, it travels over TLS. No system is perfect, but we keep the amount of data involved as small as the app allows.
- 09
Children
Rated 4+ and designed for the Apple Kids category. The app complies with COPPA and Apple's Kids category rules: no behavioural advertising, no third-party analytics, no external links or purchases reachable by a child, and no collection of personal information from children.
- 10
Your rights (GDPR and KVKK)
You may ask for access to any personal data we hold about you, ask for it to be corrected or deleted, object to processing, ask for portability, and withdraw consent. Where the app holds everything on your device, you exercise those rights directly: edit or delete the content in the app, or delete the app. Write to us and we answer within 30 days.
- 11
Payments
Fun Math is free to download. The free version can show ads; an optional Premium upgrade removes all ads and unlocks more themes. The store, subscriptions and every external link sit behind a parental gate, so a child cannot buy anything or leave the app without an adult. Purchases are handled by Apple — we never see payment details. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period, in the Apple ID account settings.
- 12
Parental gate
Anything that leaves the app — a support message, the App Store, this document — sits behind a parental gate so a child cannot open it unaided.
- 13
No links out, no chat
There is no chat, no user-generated content, no social feature and no way for a child to contact anyone through the app.
- 14
Changes and contact
Material changes to this policy are published on this page with a new date. Questions about Fun Math: Color Calculator and this policy go to https://denix.studio/contact or g.alpatar@gmail.com and are answered by a person, usually within two working days.

Apple

Any claim about the app is directed to us, not to Apple.
- 11
Governing law
These terms are governed by the laws of the Republic of Turkey, without regard to conflict-of-law rules. Disputes are resolved in the courts and enforcement offices of Bursa. Mandatory consumer-protection rights in your own country are unaffected.
