Adon AI

Privacy Policy

Last updated November 9, 2026

Adon AI is a personal health and fitness coach. This policy explains what we collect, why, who helps us process it, and the control you have. The short version: your data is used only to coach you, it is never sold, and you can export or delete all of it from the app at any time.

What we collect

• Account: your email address and sign-in details (or the identifier Apple or Google gives us if you sign in with them).
• Setup answers: name, age, sex, height, weight, target weight, goals, training and work schedule, equipment, injuries or limitations you mention, food preferences and dietary choices.
• What you log: meals and food photos, water, workouts and sets, weight and body measurements, body scans, progress photos, custom trackers you create, and your messages to Adon.
• Sleep schedule (optional): your usual bedtime and wake time, if you set them, so Adon stays quiet while you sleep and counts late-night logs toward the right day.
• Health and wearable data you choose to connect through Apple Health or Health Connect: heart rate, resting heart rate, heart rate variability, sleep and sleep stages, steps, active calories, exercise minutes, blood oxygen, respiratory rate, VO₂ max, weight, body fat and blood glucose.
• Cycle tracking (optional): period start dates you log, or menstrual flow you choose to import from Apple Health, and the cycle estimates Adon makes from them.
• Calendar (optional): if you connect it, the start and end times of busy events over the next week. Event titles, locations, notes and attendees are never read or stored.
• Location (optional): see “Location” below.
• Crews (optional): if you join a crew, your posts, reactions, check-ins, challenge and program progress, and what you share with crewmates.
• Lab results you upload: the report file (PDF or photo) and the values read from it.
• What Adon learns: notes and patterns Adon saves to personalize coaching. You can see and delete them in Profile → Autopilot & memory.
• Technical data: error reports (the page and error message, plus your account ID if you are signed in) and basic usage counts so we can fix problems and keep AI costs fair. We do not use advertising or tracking tools.

How we use it

Only to provide Adon to you: building training and meal plans, estimating nutrition from photos, computing readiness and trends against your own baseline, detecting patterns and changes, tracking milestones, sending the alerts you turn on, and answering you in chat. We do not use your data for advertising, and we do not sell or rent it.

When you log a food you picked from a food database, its name (for example “Chipotle chicken burrito bowl”) may be added to a shared list of food suggestions once several people have logged it. Only the database food name is shared — never who logged it, when, how much, or anything you typed yourself.

Location

Location is off unless you turn it on, and you can turn it off at any time — doing so deletes your saved places.

• Weather: your rough area (rounded to about 1 km) is saved so Adon can check the weather before suggesting outdoor exercise.
• Your gym: the gym you pick (rounded to about 100 m) is saved. While the app is open, Adon compares your current position with it on your phone to offer today’s workout when you arrive.
• Arrival while Adon is closed (iPhone, optional): if you turn this on and allow “Always” location, your iPhone watches the area around your gym. When you walk in, the phone sends Adon only that you arrived, using a code you can revoke by turning the feature off. Your location itself is never sent.
• Gym check-ins (optional): if you choose to, your crew is told when you arrive at the gym (at most once a day). They never see where your gym is.
• Gym search: what you type and your rough area (or, if none is saved, an approximate location from your internet connection) are used to find nearby gyms.

We never keep a location history, track you between places, or use location for advertising.

Crews and what others can see

Crews are private groups you join by invite. Crewmates can see your display name and username, your posts and reactions, whether you trained, challenge and program progress, milestones, gym check-ins if you turned them on, and your training plan’s workouts if you choose to share it. They never see your weight, body measurements, photos, meals, health or wearable data, cycle data, lab results or conversations with Adon. You can leave a crew at any time. Posts may be checked automatically to keep crews safe.

Camera, microphone and form tracking

When you talk to Adon, your phone’s built-in speech recognition turns your voice into text; only the text is sent to Adon and no audio is stored. When you use live form tracking during a workout, the camera feed is analyzed on your device and is not uploaded or stored. Photos you choose to save (progress photos, body scans, meal photos, lab reports) are uploaded as described below.

Who processes data for us

• Supabase stores your account, data and files (database and private file storage).
• Vercel hosts the app and runs our servers.
• OpenAI (and, if we switch providers, Anthropic) generates coaching, reads food photos, nutrition labels, body scans and lab reports, produces Adon’s voice, and screens messages for safety. Only the data needed for a request is sent, and our provider terms do not allow it to be used to train their models.
• FatSecret, USDA FoodData Central and Open Food Facts provide food, barcode and recipe data. Only search terms, barcodes and food names are sent, never your personal data.
• Open-Meteo provides weather forecasts. Only your rough area is sent, with nothing that identifies you.
• Photon (OpenStreetMap data, operated by Komoot) powers gym search. Only your search text and rough area are sent, from our servers, with nothing that identifies you.
• Apple, Google and browser push services deliver the notifications you turn on.

These providers act on our instructions and may not use your data for their own purposes. We may disclose data if required by law, or to protect someone’s safety.

Apple Health and Health Connect

• Adon only reads the data types you approve, and you can revoke access anytime in Apple Health or Health Connect settings.
• Health data is used only for the features you use in Adon. It is never used for advertising or marketing, never sold, and never shared with data brokers.
• Adon does not write to Apple Health or Health Connect.
• Cycle and reproductive health data is never shown to crewmates, never used for advertising, and is deleted with your account or when you turn off Profile → Cycle tracking.

Consumer health data

Much of what Adon handles is consumer health data under laws such as Washington’s My Health My Data Act. We collect it only to provide the features you ask for, share it only with the processors listed above, and you can access, export or delete it at any time as described below.

Storage and security

Data is encrypted in transit and at rest. Row-level access rules ensure each account can reach only its own records, and your files are stored in private buckets that are never public. Data is stored in the United States.

How long we keep it

We keep your data while your account is open. When you delete your account, your records and files are removed from our live systems immediately, and from backups within 30 days. Error reports are kept for up to 90 days.

Your choices and rights

• Export: Profile → Privacy & data → Download my data gives you a copy of everything in your account.
• Delete: Profile → Privacy & data → Delete my account permanently removes your account, data and files.
• Correct: edit your setup answers, logs and memory at any time.
• Notifications: turn alerts on or off in Profile → Devices & data.

Depending on where you live, you may have additional rights to access, correct, delete or port your data, or to appeal a decision about a request. To exercise them, email support@adon.fitness or use Profile → Privacy & data → Contact support in the app.

Children

Adon is for adults 18 and older. We do not knowingly collect data from anyone younger; if you believe a minor has an account, contact us and we will delete it.

Not medical advice

Adon is not a medical device and does not diagnose, treat or prevent any condition. Talk to a qualified clinician about symptoms, lab results or medical decisions.

Changes and contact

If we make material changes, we will tell you in the app before they take effect. Questions or requests: email support@adon.fitness or use Profile → Privacy & data → Contact support in the app.
