Privacy policy

Information collected

Your account and training

• Account information: your Sign in with Apple identifier, email address (which may be an Apple private relay address), and any name or display name you provide. Authentication credentials and connection records are used to protect access to your account.
• Training information: your routines, exercises, schedules, goals and other planning details you provide; sessions, sets, weights, repetitions, durations, effort and fatigue ratings, notes, activity entries, and plan-change history.
• Groups: groups you create or join, memberships, invitations, and display names used in those groups.
• Technical information: identifiers and timestamps needed for syncing, device timezone information, queued changes and cached training information on your device, and aggregate service performance metrics. The app backend is configured not to retain or export detailed request, console or trace logs; providers may still process independent account and security information. Changes made through a coaching connection are recorded in the app’s history and audit records.

Training profile, if you complete it

Your optional training profile includes goals, intended activities such as lifting, running and swimming, weekly activity context, experience, available time and equipment, movements to avoid, and any dated working sets you report. It helps suggest a starting workout and gives your authorized coach context for future plans. The profile is private to your account and authorized coach; it is not included in group feeds. You can edit it in Profile. Unfinished answers are kept in protected storage on your device, and saved answers are included in your account export and removed when you permanently delete your account.

Spoken workout feedback, if you choose it

When you choose “Talk about your workout” and grant microphone and speech permissions, Très Fort processes microphone audio using Apple’s on-device speech recognition. The audio stays on your device, is not uploaded, and is discarded after transcription. You can review and edit the text before saving. Only text you choose to save becomes part of your training information; unsaved transcription is not stored or sent to your coach. Saved feedback can be read by your authorized coach and is excluded from group feeds.

Apple Health, if you connect it

With the read permissions you grant through Apple Health, Très Fort reads workout information on your device and uploads workout records to its backend. Depending on the workout and available permissions, records can include the workout identifier, activity type, name, source app, start time and timezone, duration, distance, calories, elevation gain, and average and maximum heart rate. Heart-rate samples are used on the device to calculate workout heart-rate summaries.

Imported workouts support your training history and can be read by your authorized coach connection. Très Fort does not write workouts or other data to Apple Health.

Apple Health weight, if you enable Read weight

Separately from workout syncing, you can choose Read weight in Profile → Apple Health. Très Fort reads body-weight measurements from Apple Health to show your latest measurement and weight trends in Progress → Weight. These measurements stay in memory on your device: they are not uploaded to the Très Fort backend, included in account exports, or shared with your coach or groups. Turning Read weight off clears the view without deleting your measurements in Apple Health. You can also change read permissions in the Health app.

Intervals.icu, if you connect it

Très Fort stores the athlete identifier and authorization credentials needed for the connection, such as access and refresh tokens or an API key. It imports activity records and calendar events returned by Intervals.icu, including their names, dates, descriptions, durations, distances, training-load and other available activity metrics. Provider response data is also retained alongside imported records to support the integration. When returned by Intervals.icu, this can include body weight and other health metrics, device names and identifiers such as a power-meter serial number, gear and route references, attachment metadata, and provider synchronization or analysis information. These imported fields are separate from the local-only Apple Health weight view described above. Completed strength-session summaries and lifting load can be sent back to Intervals.icu.

Group safety

Blocking records the two account identifiers, time and block status so the accounts stop seeing one another’s shared profiles and activities. The operator can apply reversible group-sharing restrictions with a reason category and audit record. These controls do not delete private training records.

Support correspondence

If you email the operator, the email address, message, and information you choose to include are used to respond and resolve your request. Contact email is handled through iCloud Mail.

How information is used and shared

Information is used to authenticate you, store and synchronize your training, show workout history and progress, support your chosen integrations, enable group features, and maintain the security and reliability of Très Fort.

Third-party AI services (AI coaching connections)

Très Fort has no built-in AI and does not send your information to an AI service on its own. Your information is shared with a third-party AI service only after you approve a connection to it in Très Fort, on a screen that names the recipient and the information shared. Setting up a coach in Coach Connect also asks your permission before showing any setup step. A connection keeps access until you disconnect it.

Who receives it: the AI app you connect and its model provider. In the app’s setup, these are Anthropic for Claude and OpenAI for Codex. If you choose another compatible app, such as ChatGPT (OpenAI) or Meta AI (Meta), that app and its configured model provider receive it.

What is shared: your display name and training profile (goal, intended activities and weekly activity context, experience, training days and session length, equipment, movements to avoid and reported lifts); your training plan, schedule and plan history, plus races, trips, training blocks and other coaching settings; workout history, including sessions, sets, weights, repetitions, durations, effort and fatigue ratings; saved workout feedback and notes; activities imported from Apple Health or Intervals.icu, including heart-rate summaries, and planned Intervals.icu events; and group activity and member display names visible to you. The separate Apple Health group-sharing switch does not limit your own coach’s access. Your Sign in with Apple email, credentials, connect codes and access tokens are not shared.

How it is collected and sent: once connected, the AI app can request this information from Très Fort over an encrypted HTTPS connection at any time while the connection remains active, typically when you ask it to coach you, using an access grant tied to your account.

How it is used: to answer your coaching questions and to review, explain and adapt your training. The connection can also change your training plan and record training updates; those changes are saved to your plan history and audit records in Très Fort.

Protection by the AI service: coaching conversations happen in the AI app you choose, using your own account with that service. Information it retrieves is processed under that service’s terms, privacy policy and your account settings, and Très Fort does not control how long it keeps information already retrieved into conversations. Très Fort offers setup only for AI services whose published privacy policies provide protection for personal information equal to or greater than this policy, including not selling it and not using it for advertising; review Anthropic’s privacy policy and OpenAI’s privacy policy. If you connect a different app yourself, review its policy before approving.

Stopping it: use Profile → Disconnect all AI apps to stop future access through every connection. This does not erase conversations already held in the AI app; manage those in that app.

Partner training with iPad Station

Partner training is optional and uses two separate member accounts on iPhones and an iPad signed in to the host’s account. When the host starts partner setup and allows a joining member, the devices share the host’s selected workout, including exercise names, cues, progression and set targets, and the members’ display names, weights, repetitions and shared workout progress. This information travels over an encrypted local device connection so the iPad can display both members’ sets and rest progress. Both phones retain protected, account-scoped setup and progress information to recover an interrupted partner workout.

The joining member reviews their weights and chooses to save a separate copy of the workout in their own Très Fort account. Each phone records only its own member’s sets in the backend. Leaving the shared workout or closing Station does not delete the copied workout or either member’s own training history. The iPad’s shared display and invitation are cleared when Station closes or its account session ends; another member may still retain information already seen or copied.

The optional phone camera scanner reads the iPad’s pairing QR code locally. QR camera images are not uploaded or stored as training records. The public App Store app does not include movement-camera counting or experimental test recording.

People in your groups

When you join a group, other members can see shared workout summaries: your display name, session or workout name, completion details, set counts, selected exercise results, activity titles and notes, and available activity metrics. Private strength-session notes, per-set notes, and perceived-fatigue ratings are not included in the group feed.

Apple Health workouts are excluded from group feeds and group statistics unless you enable their separate sharing setting. That setting is off by default. Your lifting and Intervals.icu activities are governed by group membership, not by the Apple Health sharing switch. Other members may retain information they have already viewed or copied.

Service providers and the operator

Cloudflare hosts the app backend, database, and exercise-media storage. Apple handles Sign in with Apple and the Health permissions you grant. Intervals.icu and your chosen AI app and model provider receive information through the optional connections described above. AI providers may include OpenAI for Codex, Anthropic for Claude, or another provider you configure. The operator can access information as needed to operate, secure, and support the service.

These providers may process information in countries outside your country of residence. Data exchanged with the app backend travels over HTTPS. Your device also keeps local account and training state to support the app. No advertising SDK or third-party behavioral analytics is included in the app.

Your choices and controls

• Export: use Profile → Account → Download account data to save your profile and training information. The export excludes credentials, access tokens, invite codes, and other members’ private information.
• AI coaching: use Profile → Disconnect all AI apps to revoke your authorized coaching connections. You can also remove the connection and manage past conversations in each AI app. Generating a new connect code does not revoke existing connections.
• Apple Health: disconnect Apple Health in Très Fort to stop future syncing. Workout syncing and Read weight are separate controls. Turn off Read weight to clear the local weight view. You can separately revoke read permissions in Apple’s Health settings and turn off Apple Health group sharing in Très Fort.
• Intervals.icu: disconnect the integration to stop future syncing and clear the credentials stored for the connection.
• Groups: leave a group to end your membership, report concerns from group settings or shared activity details, and block another member. Manage your blocks in Profile → Group safety. Shared text uses a limited English objectionable-term filter; it cannot detect every abusive phrase. Reports open an email draft containing reference IDs for you to review and send. Reports are checked daily and actionable abuse is addressed within 24 hours. Blocking also applies to future group information accessed by your coach; it cannot erase earlier views, exports or conversations. Apple Health group sharing can be changed separately.
• Correction or help: edit supported training records in the app or email nick@tresfort.app for help with access, correction, or deletion requests.

Retention and account deletion

Training history is kept so that you can review it and adapt future training. Disconnecting an integration stops future access or syncing; it does not automatically delete the training information already imported into Très Fort. Removing individual training entries may hide them using deletion markers while retaining underlying records for synchronization and history.

To delete your account, use Profile → Account → Delete account and follow the confirmation and any sign-in prompts. Account deletion removes your profile, plans and plan snapshots, sessions, set logs, imported activities and events, notes, audit records, stored integration credentials, coach authorizations, group memberships, associated blocks and sharing restrictions from the active app database. Shared groups with other members can continue under another member.

Minimal deletion receipts and, for the operator’s account, a hashed identifier may remain to prevent a deleted account or repeated request from restoring access. Operational logs, provider backups, and support correspondence are separate from the active training database and may persist after active records are deleted. Contact the operator for questions about these records; this policy does not promise an immediate purge from all backups.

Deleting your Très Fort account does not delete the source workouts in Apple Health or Intervals.icu, information already sent to those providers, or AI conversations. Manage those copies with the respective service. You can also request account-deletion help by emailing nick@tresfort.app.
