Terms of Service

Last updated: September 20, 2026

CleanSketch (“we,” “our,” or “us”) provides the mobile application “CleanSketch” (the “App”). Please read these Terms before using the App.

1. Acceptance

By using the App, you agree to these Terms. If you do not agree, do not use the App.

2. Eligibility

You must be at least 13 years old to use the App.

3. Account

Some features require Google Sign-In. You are responsible for activity under your account.

4. User Content

You retain ownership of drawings you create. If you enable cloud backup, you grant us permission to upload and restore those files to and from your Google Drive solely to provide that feature. We do not claim ownership of your artwork and do not use it to train AI models.

5. CleanSketch Pro

Pro is a one-time in-app purchase billed through Google Play (cleansketch_pro_lifetime). It unlocks an ad-free experience, custom canvas size, and all particle effect brushes. There is no subscription and no auto-renewal. Restore purchases through Google Play on the same account. Refunds follow Google Play policy.

You may also watch a rewarded advertisement to unlock Pro features on that device for one day. That temporary unlock is not a purchase and does not transfer.

6. Ads

Free users may see app-open ads. Rewarded ads are optional and shown only when you choose to watch them for a one-day Pro unlock. Pro users do not see ads.

7. Prohibited Conduct

Do not use the App for illegal activity, or to interfere with the App or its servers.

8. Intellectual Property

The App (excluding your drawings) remains the property of GZLL Studio and its licensors.

9. Disclaimer

The App is provided “AS IS” without warranties of any kind.

10. Limitation of Liability

To the maximum extent permitted by law, GZLL Studio is not liable for indirect, incidental, or consequential damages arising from your use of the App.

11. Changes

We may update these Terms. Material changes will be indicated by updating the date above.
