- Beta testers and coffee supporters may have extended free access as indicated in their account.
- Subscriptions are processed through PayPal. Payments extend your account validity by the purchased duration.
- Refunds are not provided once a subscription period has begun.

4. Acceptable Use & Fair Usage Policy
You agree not to:
- Abuse, spam, or exploit the bot.
- Interfere with, reverse engineer, or tamper with the Service.
- Use the Service for unlawful, harassing, hateful, or fraudulent activities.

Fair Usage:
- Lingo Echo is intended for normal-sized Twitch communities.
- Accounts generating extreme chat volumes (e.g., very large streamers receiving multiple hundreds of messages per minute) are not supported under standard subscriptions. These may be considered enterprise accounts and require a separate agreement.
- Lingo Echo reserves the right to automatically leave channels that exceed fair usage to maintain stability for all users.
- Running the bot in multiple channels or attempting automated/bulk translations outside Twitch live chat is prohibited.

5. User-Generated Content
- By using the Service, you allow us to temporarily process your Twitch chat messages for translation and interaction.
- Chat logs are not permanently stored except for features like “memory replies,” which can be reset at any time using commands.
- To provide features such as the !summary command, Lingo Echo temporarily logs public chat messages while your stream is live. These logs are stored only during the broadcast and are automatically deleted once the stream goes offline. They are never stored permanently.
- Stream metadata (title, game, etc.) may be used temporarily to improve translation or contextual replies.
- Screenshots (if enabled) may be captured during live streams but are deleted after the stream ends.
- You retain ownership of your content.

6. Disclaimers
- The Service is provided “as is” without warranties of any kind.
- Lingo Echo uses AI-based technology. As with all AI services, it may produce unpredictable, incorrect, misleading, biased, or inappropriate responses. It may fail to respond, ignore input, or otherwise behave in ways not intended by its developers.
- You understand and accept that the Service can, at times, generate inaccurate translations, hallucinated information, or other unexpected outputs.
- Lingo Echo’s AI responses are generated automatically and may not reflect the views of Lingo Echo or its developers
- We are not responsible for translation errors, interruptions, or third-party actions.
- Twitch, PayPal, AI API provider or data-house outages may affect service availability.
- Use of the Service is also subject to our Privacy Policy.

7. Limitation of Liability
In no event shall Lingo Echo, nor its developers, affiliates, or partners, be liable for indirect, incidental, or consequential damages arising from the use of the Service. The maximum total liability, whether in contract, tort, or otherwise, shall not exceed the amount of one (1) 30-day subscription payment.

8. Termination
We may suspend or terminate access if you violate these Terms or exceed fair usage.

9. Changes
We may update these Terms at any time. Updates will be reflected by a revised “Last updated” date. Continued use of the Service after updates constitutes agreement to the new Terms.

10. Contact
If you have questions about these Terms, contact us via Discord.

Effective Date: December 4th, 2025

1. Information We Collect
When you connect your Twitch account, we collect your Twitch ID, username, preferred language settings, the link to your Twitch profile image, and whether the bot is active in your channel. In addition to this, Lingo Echo also stores your preferences - such as automatic shoutout names, moderation settings, account creation date, subscription or trial status, expiration date, and similar configuration details.

To support context-aware features (such as translations, smart replies, and shoutouts), the bot may temporarily access your public Twitch bio, recent game titles, recent stream titles, and most popular clips.

If you are live, Lingo Echo may also capture periodic screenshots of your stream (if enabled by the streamer). These are used only to provide chat context for @Lingo_Echo interactions. Screenshots are never stored permanently, shared, or sold, and are automatically deleted after your stream goes offline.

All message processing is limited to public chat messages. We do not access whispers, private messages, or any non-public Twitch data.

To provide features such as the !summary command, Lingo Echo temporarily logs public chat messages while your stream is live. These logs are stored only during the broadcast and are automatically deleted once the stream goes offline. They are never stored permanently.

For your viewers who use @Lingo_Echo, the bot will keep a short-term memory of past conversations to improve replies. This memory is separate from translations and can be deleted at any time by the viewer using the !LingoForgetMe command in your stream. As the streamer, you can delete all stored conversation history for every user who has interacted with the bot in your stream by using the !LingoForgetAll command. When !LingoForgetMe or !LingoForgetAll are used, the bot must be present in your channel to process these commands.

2. Message Processing
Messages are passed through AI API for translation in real time. In development, limited logging may be used to improve accuracy, but in production messages are processed only until the translation is delivered. Messages logged in development are deleted permanently after needed analysis.

3. Cookies and Analytics
We do not use tracking cookies or third-party analytics tools.

4. Sharing Data
We do not sell, rent, or share your data with third parties.

5. Data Retention
User preferences and aggregate stats are stored in json files. Contextual Twitch data such as bios, game and stream titles, and periodic stream screenshots are stored temporarily in memory and are deleted as soon as your stream ends. They are never stored permanently. You can revoke bot access at any time from your Twitch settings: https://www.twitch.tv/settings/connections.

6. Your Rights
You may delete your preferences or disable the bot at any time by updating your settings.
You may request deletion of any stored data or preferences at any time. If you are located in the EU or similar jurisdictions, you also have the right to access, correct, or restrict processing of your data.

7. Contact
