TavernMate: Bring Your Own Key · Go & Er co.

Privacy Policy

Last updated November 4, 2026 Effective November 4, 2026

This Privacy Policy describes how TavernMate (“we”, “our”, or “the App”), developed by Go & Er co., handles your information and respects your privacy.

By downloading, installing, or using TavernMate, you agree to the collection and use of information in accordance with this Privacy Policy.

1. Overview & BYOK (Bring Your Own Key) Architecture

TavernMate is an open client interface designed for roleplay, character management, and interactive conversation with third-party Large Language Model (LLM) providers and audio synthesis services.

TavernMate operates on a “Bring Your Own Key” (BYOK) model:

  • We do not operate central proxy servers that store your chat content.
  • We do not train artificial intelligence models on your private conversations.
  • When you enter an API key for a supported service (such as Google Gemini, Anthropic Claude, OpenAI, DeepSeek, xAI Grok, OpenRouter, or ElevenLabs), that key is stored locally on your device and is used solely to establish direct, encrypted (HTTPS) connections between your device and the respective third-party provider.

2. Information We Do NOT Collect

  • Personal Identity Information: We do not require you to create a proprietary account with an email address, password, or phone number.
  • Chat Logs & Story Content: Your messages, character cards (JSON / PNG), story branches, user personas, and settings are stored locally on your device in your private app sandbox. We cannot view, access, read, or sell your roleplay transcripts.
  • API Keys: Your third-party API keys are stored solely in your device’s private local storage (SharedPreferences) and are never transmitted to our servers or any unauthorized third party.

3. Information Collected by Third-Party Services

To provide monetization, payment processing, and core AI functionalities, TavernMate integrates trusted third-party SDKs. These third parties may collect certain data in accordance with their own privacy policies:

A. Google Play In-App Billing (Google LLC)

If you purchase the optional Lifetime VIP Pass, the transaction is handled directly and securely by the Google Play Store.

  • We do not collect or store your credit card numbers, billing addresses, or banking information.
  • Google Play provides our application with an anonymous purchase token to verify that your Lifetime VIP status is active.
  • Google Privacy Policy: policies.google.com/privacy

B. Google AdMob (Google LLC)

TavernMate displays optional rewarded video advertisements to allow users to replenish their daily message quota.

  • Google AdMob may collect and use pseudonymous device identifiers (such as Android Advertising ID), IP addresses, and general diagnostic information to serve advertisements and prevent fraud.
  • Google AdMob Privacy Policy: policies.google.com/technologies/ads

C. Third-Party AI & Audio Providers (User-Configured)

When you submit a message or request text-to-speech generation, your prompts, context, and character definitions are sent directly via encrypted HTTPS to the API provider you have chosen to configure:

Each provider processes and retains data according to their individual API Terms of Service. Most commercial API tiers do not use API data to train their models.

4. Device Permissions

TavernMate requests minimal device permissions strictly necessary to execute its advertised features:

  • INTERNET & ACCESS_NETWORK_STATE: Required to transmit chat requests to your chosen AI providers, stream text responses, load ElevenLabs audio, and verify in-app purchases.
  • READ_EXTERNAL_STORAGE (Android 12 and below) / Photo Picker: Required only when you voluntarily import Tavern character cards (PNG / JSON) or select a custom wallpaper/avatar from your gallery.
  • BILLING (com.android.vending.BILLING): Required to allow Google Play In-App Billing for the Lifetime VIP pass.

5. Data Security & Storage

  • All user-generated content (character lore, memories, chat sessions, user personas) resides in internal application storage on your local physical device.
  • Clearing application cache/data or uninstalling the app will permanently remove your locally stored character data and settings unless you have exported your character cards as backup PNG or JSON files.

6. Children’s Privacy

TavernMate is not directed at children under the age of 13 (or under 16 in the European Union). Because the app connects to open-ended third-party generative artificial intelligence APIs with user-configured parameters, we do not knowingly collect personal information from children. If you are under the required age of legal consent in your jurisdiction, you must not use this application.

7. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. Any changes will be posted on this page with an updated “Last Updated” date. We encourage you to review this page periodically for any updates.
