Privacy Policy

Last updated: October 20, 2026

1. Who we are

Spanda ("Spanda", "we", "us") is a menstrual cycle tracking app for iOS and Android, developed by Elizaveta Kovalenko.

Questions about privacy? Contact us at supportspanda@gmail.com.

2. Your cycle data — stored only on your device

The information you track in the app — your period dates, cycle length, journal notes, and preferences — is stored locally on your device. It is not uploaded to us and not stored on our servers. We cannot see it, and neither can anyone else.

Menstrual and reproductive health information is deeply personal. Because we never receive it, we cannot disclose it — to advertisers, data brokers, or in response to any legal request.

3. What we do keep — only for subscriptions

If you create an account to manage a subscription purchased on our website, we store the minimum needed to make that work:

• A sign-in identifier — your email, or an anonymous ID from Sign in with Apple / Google.
• Subscription status — whether your subscription is active and until when.

That's it. We do not store any cycle data, journal notes, or health information on our servers. This account layer is used only to confirm that you have access to Premium features.

4. Service providers we use

To run subscriptions, we rely on a small number of trusted providers who process only the data described above:

• Paddle — processes web payments as our Merchant of Record. Paddle handles your payment details and taxes; we never receive your card information. See Paddle's Privacy Policy.
• RevenueCat — manages subscription status across platforms.
• Supabase — stores your sign-in identifier and subscription status.
• Apple and Google — process in-app purchases and, with your permission, provide sign-in and calendar access, under their own policies (Apple, Google).

5. Calendar access

With your permission, Spanda writes daily cycle information (cycle day, phase, and short tips) into a calendar you choose (Apple Calendar or Google Calendar). This stays within your own Apple or Google account, under their policies. You can revoke calendar access at any time in your device settings.

6. Payments

Web payments are handled by Paddle; in-app purchases by Apple or Google. We never see, receive, or store your card number or billing address. Anonymous, aggregated sales statistics may be shared with us; these do not identify you.

7. How to delete your data

• Cycle data and notes — delete them in the app (Settings → Reset), or uninstall the app to remove all local data.
• Your account — you can delete your account from the app's Account screen; this removes your sign-in identifier and subscription record from our side.

8. Children

Spanda is not directed at children under 13, and we do not knowingly collect information from children.

9. Your rights

Privacy laws such as the GDPR and CCPA give you rights over your personal data. Because we hold only a sign-in identifier and subscription status, these are the only items we can access, export, or delete on your behalf — and you can delete them yourself from the Account screen. Your cycle data remains on your device, under your control, at all times. We do not sell personal information or engage in cross-app tracking.

10. Security

Your cycle data is protected by your device's own security (passcode, Face ID / Touch ID, device encryption). Account data on our side is stored with reputable providers using encryption in transit and at rest.

11. Changes to this policy

We may update this policy from time to time. When we do, we will revise the "Last updated" date above and, for significant changes, notify you in the app.
