Private AI companions: who keeps your chats and who trains on them

If privacy is your first filter, Secrets AI comes out ahead among hosted services on deletion: its policy says chat history is "deleted immediately upon account deletion", and data is encrypted at rest. Chub AI's terms say private chats are never used to train a model, and it takes crypto only, so there is no card line at all. If you want no copy on anyone's server, only a local setup on your own computer does that. We compared 7 services on 4 points taken from their own policies, checked October 23, 2026.

We read each service's privacy policy, terms and help pages on October 23, 2026, from a US connection, logged out, and took four answers from them: does the operator train on chats, how do you delete the account, what stays behind, and what appears on your card. Policy dates are in the References. We did not buy plans or test deletion; a policy is a promise, not an audit.

Only services from our recommended list are ranked. Order follows the four points: fast deletion and clear training rules first, then vaguer policies. For the background, read the AI companion privacy guide, the data breaches list and the billing guide.

OurDream and HammerAI are not included while we re-check their character catalogs (Oct 23, 2026).

Secrets AI

The Privacy Policy says chat history is "deleted immediately upon account deletion" and data is encrypted at rest (AES-256). It also lists training among data uses, with no opt-out described. Free gives 20 messages a day; Premium is $19.99/mo. Minus: the homepage advertises "end-to-end encryption", which the policy does not describe.

Chub AI

The terms say private characters and chats will never be "used for training an AI model, or any other purpose beyond providing the Services." Payment is crypto only, at $20/mo for one plan, so nothing shows on a card. The minus: no retention period is published and the deletion path is not visible on public pages. If you connect your own model key, that provider's policy applies too.

Nastia AI

Account deletion sits in Account Settings, takes effect immediately and cannot be undone (Privacy Policy, September 16, 2026). You can also delete single chats, images and videos at any time. Minus: payment records, and chats of accounts that broke the rules, can be kept up to 7 years, and plan prices only appear after sign-in.

Kindroid

The policy (October 22, 2026) says: "We will not sell or share your Personal Data." Chats are encrypted at rest and in transit, not end to end. It does not say whether chats train models, and deletion runs through contacting the company, not a button. Prices appear only at checkout. Official site in the References; we have no partner link.

Nomi

The policy (April 27, 2026) gives a deadline: personal data is removed about 28 days after you confirm deletion. What stays is the training and communications archive, which the policy says "would no longer be attributable to you". Nomi does not publish prices on a pricing page. Official site in the References.

DreamGF

The policy says staff review chats only if you report a problem with one, and data is processed in the EEA. The pricing policy promises "no adult transactions on bank statements." Minus: no fixed retention period, and the homepage "strictly private" line is marketing, not the binding document. The first month is $12.99, then $25.98/mo.

Candy AI

Candy is the weakest pick on training: the Privacy Notice (October 19, 2026) uses de-identified chats to train models, with possible human review. It is the most open about billing, though: the plans page and help center say the charge shows as "EverAI". Deletion is self-serve and cancels the plan. The annual plan works out to $3.99/mo.

• "End-to-end encryption" on a homepage. Secrets AI says it in marketing copy, but its policy only describes encryption at rest and in transit. With a hosted model, the operator's servers have to read your text to answer it.
• "Private" meaning "hidden from other users". A private character setting controls who sees the chat, not whether the operator can.
• Your own API key or a proxy. On Janitor AI and similar platforms, every message also goes to the model provider you connect, under its policy. See is Janitor AI safe.
• Chats stored next to your email. Muah.AI is the warning case: in September 2024 about 1.9 million email addresses leaked together with users' prompts. We do not recommend it. Details are on the Muah.AI safety page.

If you cannot accept any copy of your chats on someone else's server, skip every hosted service on this list and use a local setup. Our local AI chat guide (/best/local-ai-chat/, publishing alongside this page) covers the hardware side.

Which AI girlfriend app is the most private?

A local model on your own computer is the most private option: chats stay on the device and work offline (see /best/local-ai-chat/). Among hosted services, Secrets AI deletes chat history immediately with the account, and Chub AI's terms rule out training on private chats.

Can I chat with an AI companion anonymously?

Partly. Hosted services need at least an email; use a separate address with no real name, and remember that card payments link to you unless you pay through crypto, as Chub requires.

Do AI companion apps train on my chats?

Some say yes outright (Candy AI, Secrets AI), some say no (Chub AI for private chats), and several policies do not say (Kindroid, DreamGF). If the policy is silent, assume it is possible.

Does deleting my account erase everything?

Rarely. Secrets AI and Nastia AI delete chat data right away, but keep payment records for years; Nomi keeps anonymized archives. Cancel the plan first, then delete, then ask the privacy contact to confirm.

What will show on my card statement?

Candy AI names "EverAI". DreamGF promises no adult wording but no exact name. Most others publish nothing. App store purchases show under the app's name in your Apple or Google history.
