Privacy and security
You stay in control
Replog only connects to an assistant with your consent, and you can remove that access at any time.
Your own account
The assistant sends you to Replog: you sign in, then tap “Autoriser” (Authorize) on a screen that shows what it is asking for. No password is shared with the assistant.
Data specific to each user
Each connection is tied to one account: the assistant only reaches the data of the account that authorized it. Replog doesn't sell or share your data.
What the assistant sees
Only what its tools return for your account. That information is then processed by the assistant's publisher (Anthropic or OpenAI) under its own privacy policy.
Revocable immediately
In Profile → Connected assistants (“Profil → Assistants connectés” in the French interface), “Retirer l'accès” (Remove access) makes the assistant's access unusable right away, without waiting for its connection to expire.
View or change: what the assistant can do
Replog exposes 30 tools to the assistant. They fall into three families depending on what they do to your data.
Read-only: these tools change nothing.
- View profile
get_profile - See the program format
get_program_format - List weeks
list_weeks - Check a week
preview_program - View a week
get_week - View a session
get_session - See the weekly report
get_weekly_report - View a day
get_day - See tracking history
get_history - List tracked exercises
list_exercises - See an exercise's progress

They add or reorder things without overwriting anything.
- Create a week
create_week - Duplicate a week
duplicate_week - Add a session
add_session - Add an exercise
add_exercise - Reorder an exercise
move_exercise - Add a meal
log_food
They can replace, erase or delete existing data. Deleting sets you've already completed requires an explicit confirmation, and an import never replaces a week that already has results.

update_profile - Edit a week
update_week - Edit a session
update_session - Edit an exercise
update_exercise - Set planned sets

save_weekly_feedback - Delete a week
delete_week - Delete a session

- ChatGPT: actions that change data ask for your confirmation by default (OpenAI documentation).
- Claude: you decide whether to approve actions and can turn off tools you don't need (Claude documentation).
How to disconnect Replog
- 1
From Replog (recommended)

Profile → Danger zone (“Zone de danger”) → “Supprimer mon compte” (Delete my account) permanently erases the account and the copy of your data on the server.
FAQ
Frequently asked questions
Do I need a Replog account?
Yes. The assistant connects to your Replog account: create one at replog.fr with an email address or, when it is offered, with Google. The assistant can only read the data that exists in your account.
Which assistants are compatible?
Claude and ChatGPT, through a remote MCP server with OAuth sign-in. Other assistants that support remote MCP servers may work, but only Claude and ChatGPT are documented here.
Is Replog in the official Claude and ChatGPT catalogs?
Not yet: both submissions are in progress. Until then, you can connect Replog yourself by adding it as a custom server, as explained above. This page will be updated when it is published.
I can't find the option to add a custom server
Availability depends on your plan and your organization's rules. On Claude, Team and Enterprise plans reserve adding connectors for owners; on ChatGPT, adding one is done in the web version and may be restricted by the workspace. Menus also change: refer to the official help linked in each guide.
The assistant reads my data but can't change it
An account that has never been synced can be read but not changed by an assistant. Open Replog once, signed in with the same account, to enable syncing, then try again.
The assistant's changes don't show up in the app
They appear at the next sync: open the app, switch back to its tab, or tap “Synchroniser” (Sync) in Profile → Account and sync.
I see “Cette demande d'autorisation est invalide ou a expiré” (the authorization request is invalid or has expired)
The sign-in request is no longer valid. Start the connection again from the assistant (reconnect the Replog connector), then tap “Autoriser” (Authorize).
What does the assistant see, and where does my data go?
It sees what its tools return for your account. That information is sent to the assistant's publisher and processed under its own privacy policy. Without a connection from you, nothing is sent to it. The details are in Replog's privacy policy.
Does Replog give medical advice?
No. Replog is a personal logbook. If you have pain, marked fatigue or doubts about your health, see a professional.
How do I disconnect Replog?
In Replog, open Profile → Connected assistants and tap “Retirer l'accès” (Remove access): access stops immediately. You can also remove the connector in Claude or ChatGPT.
