Privacy Policy

Last updated: April 25, 2026

Publisher details to complete before submission: Sidereal is operated by [LEGAL OPERATOR NAME], [LEGAL OPERATOR ADDRESS OR JURISDICTION]. Privacy questions may be sent to [PRIVACY EMAIL].

This Privacy Policy explains how Sidereal collects, uses, shares, and protects information when you use the Sidereal mobile app and related services. Sidereal helps you create, personalize, and track routines.

Information We Collect

We collect the information needed to provide and improve Sidereal, including:

  • Account information: email address, display name, profile image, sign-in provider identifiers, verification status, and account timestamps.
  • Authentication information: sign-in session data and related security information used to keep your account accessible and protected.
  • Onboarding answers: goals, preferences, selected routine inspirations, schedule preferences, and related answers you provide to personalize your routine.
  • Routine data: generated or selected activities, checklist items, activity notes, time preferences, routine order, and archived activity state.
  • Progress data: completion status, checklist states, dates, and progress history for routine activities.
  • Anonymous session data: a session key used to keep your onboarding, routine, or progress available before you create or sign in to an account.
  • Subscription information: purchase status, entitlement status, product identifiers, and subscription-related events provided by the app stores and RevenueCat.
  • Device and diagnostic information: limited technical information needed to operate, debug, secure, and improve the app, such as app version, platform, and error information.
  • Support communications: messages and contact details you provide when requesting help.

How We Use Information

We use information to:

  • create and manage your account;
  • authenticate you and keep your session secure;
  • generate, personalize, save, and sync routines;
  • track routine progress and show progress history;
  • process, verify, restore, and manage subscriptions;
  • provide support and respond to requests;
  • debug, protect, and improve the app; and
  • comply with legal, safety, tax, accounting, and app-store obligations.

How We Share Information

We do not sell your personal information. We share information only as needed to operate Sidereal, comply with law, or protect the app and users.

  • Convex: backend database, account-related app data, session-linked app data, and server functionality.
  • Better Auth and sign-in providers: authentication services, including Apple and Google sign-in where you choose those providers.
  • RevenueCat: subscription entitlement management, purchase status, product identifiers, and subscription events.
  • Apple App Store and Google Play: payment processing, subscription management, refunds, and app-store compliance.
  • Cloudflare Pages: hosting for these legal and support pages.
  • Support providers: email or customer-support tools used to respond to your messages.
  • Legal and safety recipients: authorities, advisors, or other parties when required by law or necessary to protect rights, safety, and security.

Payments

Payments are processed by Apple App Store or Google Play, depending on your device and purchase flow. Sidereal does not receive or store your full payment card number. We receive subscription status and entitlement information needed to unlock paid features.

Data Retention

We keep personal information for as long as needed to provide Sidereal, maintain your account, resolve disputes, comply with legal obligations, and enforce our terms. Routine, onboarding, and progress data are generally retained while your account or anonymous session remains active. Subscription and transaction records may be retained longer where required for app-store, accounting, fraud prevention, tax, or legal reasons.

Account Deletion

You may request deletion of your Sidereal account and associated personal data through our account deletion page. We will delete or de-identify account data unless retention is required or permitted for security, fraud prevention, legal compliance, tax, accounting, dispute resolution, or app-store obligations.

Your Choices and Rights

Depending on where you live, you may have rights to access, correct, delete, restrict, or receive a copy of your personal information, or to object to certain processing. To make a privacy request, contact us at [PRIVACY EMAIL].

Security

We use reasonable administrative, technical, and organizational safeguards designed to protect personal information. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

Children

Sidereal is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child provided personal information, contact us so we can take appropriate action.

International Use

Sidereal may process information in countries other than the country where you live. Where required, we use appropriate safeguards for international transfers.

Changes to This Policy

We may update this Privacy Policy from time to time. If changes are material, we will take reasonable steps to notify you, such as updating the date above or providing in-app notice where appropriate.
