Zerva — AI Tarot & Card Reading
Last updated: July 22, 2026

This Privacy Policy explains how the Zerva mobile application (“Zerva”, “the app”, “we”, “us”, or “our”) collects, uses, and protects your information. By using Zerva, you agree to the practices described here. Zerva is provided for entertainment and self-reflection purposes only and does not provide medical, legal, financial, or psychological advice.

1. Information We Collect

Information you provide. During onboarding and use, you may provide:

A first name or nickname you choose to enter;
Your birth date (used to show your zodiac sign) and reading preferences (topics, tone, reminder time);
The questions you ask for a reading and the messages you send in reader chats.

Account. Zerva uses anonymous authentication. We do not require an email address, password, phone number, or social login to use the app. A random anonymous identifier is created to save your readings and preferences to your account.

Automatically collected. We collect limited technical and usage data:

App activity — app events such as screens viewed and features used;
Purchase history — your subscription status and transaction records (never your card number, which only the app store sees);
Device and other identifiers — an anonymous app instance identifier and a device attestation token (Play Integrity on Android, App Attest on iOS) used to protect our servers from abuse.

We do not collect your location, contacts, calendar, photos, files, health data, or browsing history, and Zerva does not use an advertising identifier.

2. How We Use Your Information

To generate personalized tarot readings, interpretations, and reader conversations;
To save your readings, journey, and preferences so they are available across sessions;
To send the daily ritual reminder you opt into;
To operate, secure, and improve the app and understand how features are used;
To manage subscriptions and prevent fraud and abuse.

3. AI Processing

Zerva’s readings and chat responses are generated by third‑party artificial‑intelligence services. To produce a reading, the cards drawn, your reading question, and your chat messages are sent to our secure server and then to an AI provider (currently routed through OpenRouter to Google and OpenAI models) solely to generate a response. Please avoid sharing sensitive personal information in your questions or messages. AI outputs are for entertainment and reflection only and may be inaccurate.

4. Third‑Party Services

We rely on the following providers, each processing data only as needed to deliver their function:

Google Firebase — anonymous authentication, database storage, hosting, and app‑integrity checks;
AI providers (OpenRouter, Google, OpenAI) — generating reading and chat text;
Mixpanel — anonymous product analytics (EU data region);
RevenueCat — managing subscription status;
Google Play and Apple — processing all payments through their respective app stores (we never see your card details).

We do not sell your personal information, and we do not use it for third‑party advertising.

5. Data Retention & Deletion

Zerva has no user accounts, so there is no account to close. Your data is stored under a random anonymous identifier and is kept for as long as you keep using the app.

How to request deletion. Email ast.developeracc@gmail.com from any address, with the subject line “Delete my data”. Because there is no account, we need your anonymous user ID to find your record: open the app and go to Profile › Help & Support, where the ID is shown with a copy button. (Tapping “Contact us” there attaches it automatically.) If you subscribed, the order number from your Google Play or Apple receipt also works. We complete deletion within 30 days and confirm by email.

What is deleted. Everything tied to your anonymous identifier: your name or nickname, birth date, reading preferences, saved readings and questions, journey entries, and analytics events.

What is retained, and for how long. Transaction records required for tax, accounting, and fraud-prevention purposes are kept by us and by the app stores for as long as the law requires (generally up to 10 years in Türkiye). Server logs containing no personal content are kept for up to 90 days. Content you reported to us for safety review is kept for up to 12 months so we can improve our filters. Anonymous, aggregated statistics that cannot identify you may be retained indefinitely.

Uninstalling the app stops further collection but does not by itself delete data already stored, and does not cancel a subscription.

6. Children’s Privacy

Zerva is not directed to children. The app is intended for users aged 18 and older and we do not knowingly collect personal information from children. If you believe a child has provided us information, contact us and we will delete it.

7. Data Security & International Transfers

We use industry‑standard measures, including encrypted transport (HTTPS) and access controls, to protect your information. Data may be processed on servers located in the European Union and the United States. No method of transmission or storage is completely secure, but we work to protect your information.

8. Your Rights

Depending on where you live (including under the EU GDPR and California CCPA/CPRA), you may have the right to access, correct, delete, or restrict the processing of your personal information, and to withdraw consent. To exercise these rights, contact us using the details below.

9. Changes to This Policy

We may update this Privacy Policy from time to time. Material changes will be reflected by updating the “Last updated” date above. Continued use of the app after changes constitutes acceptance of the revised policy.
