Do AI Companion Apps Train on Your Chats?
7 of 15 apps in our tracker permit chats to train or improve AI; 1 of 15 explicitly says they do not: Elyvie. These figures describe the 2 October snapshot. Tracker · Privacy §5(a).
A companion can retain a preference to continue your conversation without using it to train a model. Elyvie separates these uses: §5(a) excludes model training, while §5(b) describes account- and character-scoped memory.
Why choose Elyvie
- Its policy excludes conversations, uploaded images and other user content from training, fine-tuning and improving AI models.
- Rolling summaries maintain context; long-term facts retain shared interests for the specific character.
- Conversation deletion also removes associated memories and summaries from active systems, subject to the policy’s retention terms.
- Access is available on the web and Telegram. The interface supports six languages.

Check the permission behind the headline
Open the data-use section and search for “train”, “fine-tune”, “improve models” and “messages”. Identify the data involved and whose model is being improved. Replika’s snapshot evidence distinguishes proprietary safety-algorithm training and chatbot improvement from third-party model training. Its “yes” classification covers the former. Replika policy.
Next, inspect consent controls. Character.AI’s cell records an EEA/UK opt-out for new content after opting out. That scope matters when reading a training permission. Training settings.
Finally, read deletion separately. An account-deletion path describes how to remove an account; a training clause describes permitted data use. Save both sources before sharing personal context. The seven “not stated” cells remain their own category and are not counted as “no”.
