Trust / the plain version

Your cards are private. Your AI works by invitation.

Your collection is private by default. Reanthesis does not sell your study content, use it for advertising, or use it to train AI models. Another AI can reach your collection only after you approve it.

No sale No ads No training on study content

01 / What matters first

The answers you should not have to hunt for.

Start with the practical boundaries. The implementation details are farther down if you want them.

A

Who can see my cards?

Your collection is private to your account. It is not public or visible to other Reanthesis users.

B

Can staff see them?

Not as a routine matter. Access is limited to running the service, debugging a problem, or helping with a support request.

C

What reaches AI?

Only limited context for a feature you invoke, or study content within the connection you explicitly approve.

D

Can I take my work?

Yes. An earned .apkg export remains available after membership ends, with notes, images, and study history.

You own your study content. Read the exact language in our Terms and Privacy policy.

02 / Your AI, your connection

An invitation with a readable boundary.

Connected AI uses the open-source Reanthesis connector. Connecting opens a clear approval screen. You never give your Reanthesis password to the AI provider, and you can revoke the connection.

It can

  • Read cards, decks, tags, study stats, and your basic study profile.
  • Create, edit, or delete study content and upload card media.
  • Wake or rest study material when you ask it to.

It cannot

  • Change billing, membership, account settings, or your email.
  • Start imports, create exports, or submit reviews on your behalf.
  • Expand its scope silently: connector permissions default to deny.
Technical connection details

Approval uses OAuth with PKCE. Connector permissions default to deny. Connection tokens have narrow permissions, expire automatically, can be revoked, and are not stored in readable form.

03 / Two ways AI appears

One connection you choose. One helper you invoke.

Connected AI

Bring the AI you already use.

After OAuth approval, the Reanthesis MCP connector lets your selected provider make cards, organize material, wake a topic, and work with media inside the boundaries above. You still grade every review.

Built-in Describe

A small, user-invoked suggestion.

Describe sends a short statement plus limited card fronts, tags, and deck labels to an AI service provider. It proposes a card; it never writes one automatically. You decide what to keep.

04 / Security by construction

How the account is protected.

These are current implementation facts, not certification badges. The plain version comes first.

Sign-in

Passwords are hashed rather than stored as readable text. Sessions expire and are rotated.

Connections

AI connections have a narrow scope, expire automatically, and can be revoked.

Storage

Study data is stored encrypted at rest in private US AWS infrastructure. Public traffic uses HTTPS.

Images

Every image read checks account ownership first, then returns a link that expires quickly.

Technical implementation details

Passwords are hashed, sessions expire and rotate, public traffic uses HTTPS, and stored images are private. Connector approval uses PKCE, and connection permissions default to deny.

05 / Import without surrender

Anki stays yours.

Connect to Anki is local and permission-gated. It is read-only, uses AnkiConnect on your machine, and never asks for an AnkiWeb password. An .apkg upload is another path for notes, media, tags, and study history.

01

Choose
Use Anki’s own permission dialog.

02

Move
Bring the collection and history; Anki is untouched.

03

Expire
Temporary import staging expires within seven days.

06 / Keep control

Take it with you—or delete it.

A paid membership earns an export with your notes, images, and study history. That .apkg remains available after membership ends. If you delete your account, Reanthesis removes database content and attempts immediate media cleanup; staged files still follow their seven-day expiry.

Reanthesis is for personal study. Do not store patient records or other sensitive clinical data in your cards.

07 / Who handles what

When another company is involved.

No advertising trackers or third-party analytics. These services appear only where a narrow product job requires them.

08 / Straight answers

If a boundary matters, say it plainly.

Does Reanthesis train on my cards?

No. Reanthesis does not sell study content, run ads against it, or use it to train a model. Describe sends only its limited prompt context to an AI service provider when you invoke it.

Is my collection end-to-end encrypted?

No. Study data is encrypted at rest and public traffic uses HTTPS, but Reanthesis is not end-to-end encrypted. The service needs to process your collection to sync it, schedule reviews, and run features you request. Do not use Reanthesis for patient records or other sensitive clinical data.

Can a connected AI see my account?

It can read your email and basic study profile, along with cards, decks, tags, and stats. It cannot change billing, membership, account settings, imports, exports, or submit reviews.

Do you track me for advertising?

No advertising trackers or third-party analytics are used on the marketing site or in the product.

Where can I inspect the connection?
