Privacy Policy

Last updated: May 7, 2026

Rhythm is a local-first routine planning app. You can use the core manual planning features without creating an account. Optional account, cloud sync, purchases, planning credits, and AI-assisted plan drafting require sending some data to our backend and service providers as described below.

Rhythm is not a medical provider and does not provide medical advice. If you use Rhythm for medication or health-related routines, always follow guidance from your clinician or pharmacist.

Information we collect

Plan data you create, such as plan names, phases, dates, reminder times, instructions, and completion state.
Account information from Sign in with Apple, such as your Apple user identifier, and email or display name if Apple provides them.
Purchase and planning credit information, including App Store transaction identifiers, product identifiers, credit grants, and credit usage.
AI-assisted planning data when you request plan drafting or editing, including typed planning instructions, voice planning input, drafted plan updates, structured plan field changes, session identifiers, and usage metadata such as token counts.
Basic technical information needed to operate and secure the service, such as request timestamps, error logs, and authentication records.

Local-first storage

Plans created while you are not signed in are stored on your device. They are not uploaded to our backend unless you sign in and use cloud sync. Deleting the app or deleting plans in the app removes local-only plan data from that device, subject to normal device backup behavior.

Cloud sync and account use

If you sign in, Rhythm may upload your local plan snapshots to your account so your plans can be backed up and synced. Your account is also used for optional AI-assisted plan drafting, planning credit balance, purchase restoration, and account-level support.

AI-assisted plan drafting

If you request AI-assisted plan drafting or editing, your relevant plan details, AI session state, typed planning instructions, voice planning input, and drafted plan updates may be processed by our backend and by AI service providers such as Google Gemini. The assistant is used only to help convert your own routine details into structured plan fields and reminder settings. AI usage may be stored with the plan session so future plan edits can continue the same context. We also store usage metadata so planning credits can be calculated and service quality can be monitored.

Notifications and Live Activities

Rhythm uses iOS notification and Live Activity capabilities to show reminders, lock screen cards, and Dynamic Island status. These features are handled by the operating system on your device. Reminder content may appear on your lock screen according to your iOS notification settings.

Purchases and planning credits

Purchases are processed by Apple through the App Store. We receive purchase validation information necessary to grant planning credits and restore purchases. We do not receive or store your full payment card details.

How we use information

To provide plan creation, reminders, completion tracking, cloud sync, and account support.
To authenticate accounts and protect the service from abuse.
To verify purchases, grant planning credits, and calculate optional AI-assisted planning usage.
To provide AI-assisted plan drafting and editing when you request it.
To diagnose errors, maintain reliability, and improve the product.

Sharing

We do not sell your personal information. We share information only with service providers needed to operate Rhythm, such as Apple for sign-in and purchases, Cloudflare for hosting and backend infrastructure, and AI providers for optional AI-assisted plan drafting.

Data retention and deletion

We retain account, sync, purchase, planning credit, and AI-assisted planning session data for as long as needed to provide the service, comply with legal obligations, resolve disputes, and prevent abuse. You can request deletion of cloud account data by emailing juvenijah@gmail.com with the subject “Delete Rhythm Data”.

Security

We use reasonable technical and organizational safeguards to protect data. No system is perfectly secure, and you should avoid storing sensitive information in plan titles or instructions unless needed for your own use.

Children

Rhythm is not directed to children under 13. If you believe a child has provided personal information, contact us so we can review and delete it where required.

International processing

Your information may be processed in countries or regions other than where you live. By using Rhythm, you understand that data may be transferred and processed where our service providers operate.

Changes

We may update this policy as Rhythm changes. We will update the “Last updated” date when we make material changes.
