Helpful information to include

For technical support, include your Android device model, Android version, Rhythm app version, what you expected to happen and what happened instead. Please do not email sensitive calendar content unless it is necessary to explain the issue.

Purchases

Rhythm purchases are processed through Google Play. For subscription cancellation, purchase history or Google Play payment-method issues, use the controls available in Google Play. If Rhythm does not recognize a valid purchase, contact us and include the product name and a description of the issue. Do not send full payment-card details.

Privacy and cloud sync

Rhythm is local-first. Cloud sync is optional and is enabled only after Google sign-in. You can delete the synchronized cloud copy at any time in Settings, or follow the cloud-data deletion guide. See the Privacy Policy for details.

Travel times and leave-by recommendations are estimates. Actual travel conditions may vary.

Service provider and data controller: Mad Forge Design, obrt za usluge, vl. Luka Brajković, Zagreb, Poljačka ulica 67, 10000 Zagreb, Croatia. We use Mad Forge Design as our public brand.

Sign-in does not enable calendar sync. Signing in for routes or purchase verification authenticates your Rhythm account. Uploading your private Rhythm calendar data requires separately enabling Cloud sync. Android calendar accounts are managed separately by Android and their providers.
