Ahonui
Privacy Policy
Last updated 8 September 2026
The short version. Ahonui collects the health entries you log and the goals you set, so they survive a new phone. It does not track you, does not advertise, and does not use your health data to train any model. Nothing is sold, and no one who handles your data may use it for their own purposes. Nobody sees your day unless you connect with them and you both agree, and even then they see a short, fixed summary rather than your entries. Deleting your account deletes what is on it. This website counts visits, and the app can count which screens you use, each only if you allow it and neither carrying any health data.
Subscriptions
When you subscribe, Apple processes the payment and we never see your card details. Your device sends us Apple's identifier for the purchase so we can ask Apple whether the subscription is still active. We store that identifier, the plan, its renewal date and its status. We do not receive your name, email or payment method from Apple through this.
Who we are
Ahonui is operated by Bijou Labs LLC, a Delaware limited liability company ("Bijou Labs", "we", "us"). Bijou Labs LLC is the data controller for everything described here. For privacy questions, including any request about your data, write to privacy@ahonui.app.
What Ahonui collects
Account information
When you create an account we store your email address, your name if you provide one, and an identifier from your sign-in provider. If you use Sign in with Apple and choose to hide your email, we receive and store Apple's private relay address rather than your real one.
Health and activity entries
Stored on our backend so they reach your other devices and survive reinstalling:
| Category | What is stored |
|---|---|
| Meals | Photo, optional note, meal type, timestamp, and whether it broke a fast |
| Nutrition | Calories, macronutrients, and the foods you picked from search for each meal |
| Fasts | Start time, planned length, end time, and whether it was completed or broken |
| Water | Amount and time of each log |
| Weigh-ins | Weight, time, and where the reading came from |
| Workouts | Activity type, start and end time, duration, energy burned, distance, and the source app |
| Sleep | Session start and end, duration, sleep stages, and the source app |
| Movement, by day | One row per day with the day's totals for whichever readings a movement protocol uses: steps, distance, flights, exercise minutes, active calories, stand hours, and whether the Activity rings closed. Only the readings you have chosen are sent; the phone reads the rest for itself and keeps them there. |
| Goals and settings | Calorie and macro targets, each protocol's goal, source, milestones and schedule, and display preferences |
| Block activity | Your rules, which protocols were met on a given day, and a record of each time you passed a block: which protocol, when, how far short you were, how long the block had been up, whether strict mode was on, what streak it ended, and whether you used a friend's pass. Never which app |
| Friends | Your username, who you are connected to, the invite codes you have out, a display name and picture, and the nudges sent between you |
Apple Health
If you grant access, Ahonui reads workouts, sleep, water and body weight from Apple Health, and the movement readings a protocol can be set to: steps, walking, running, cycling and swimming distance, flights climbed, exercise minutes, active energy, stand hours and the Activity summary. It writes water back. It reads nothing else. You can review or revoke any of it in iOS Settings under Health at any time; revoking does not delete what Ahonui already recorded.
Health data is never used for advertising, never sold, and never shared with a third party for their own purposes.
Screen Time and the apps you block
Choosing apps to block uses Apple's Family Controls framework, which hands the app an opaque token for each selection rather than a name or identifier. Neither we nor anyone holding our data can tell which apps you picked. The tokens are meaningful only to iOS, on your device.
Photos
Meal photos are stored with the meal. They are not analysed and go nowhere else. Ahonui reads nothing in your photo library beyond the images you select.
Usage analytics, only if you turn them on
Off unless you say otherwise. Ahonui asks once during setup, the switch starts off, and you can change it any time in Settings under Who sees you. Until you turn it on, nothing is collected, nothing is sent, and no identifier is created.
With it on, our analytics provider records which screens you reach and where you stop: finishing setup, whether you granted Screen Time, whether you chose apps to block, reaching the subscription screen and subscribing. Each of those is the fact that it happened, never a number attached to it.
It never receives your health data. Not a weight, a fast, an ounce of water, a night's sleep or a meal. It never receives which apps you block, and it never receives your name or your email address.
It does receive your Ahonui account identifier, so that the same person is counted once rather than as a stranger on every device. That identifier is a random string. It means nothing outside our own database, it cannot be turned back into your name or your email by anyone holding it, and none of the data listed above is attached to it.
Turning it off in Settings stops collection and clears the stored identifiers. Turning it back on while signed in to the same account counts you as the same person again. Deleting your account ends it.
What Ahonui does not collect
- No advertising identifier, and no tracking across apps or websites
- No location data
- No contacts, calendar, or microphone access
- No browsing history, and no record of which apps you use
This website
Everything above is the app. This site asks separately and collects nothing unless you allow it at the banner, and saying yes here says nothing about the app or the other way round. With your consent, our analytics provider records the pages you open here, how you arrived, your browser, device type and IP address, and stores an identifier in your browser so a second page counts as the same visit. It receives nothing from your Ahonui account, and an invitation code is taken out of the address before anything is sent. Change your answer at the Cookies link in any footer.
Why we process it
Every category above exists to run features you asked for. Where the GDPR applies, our legal basis is performance of our contract with you for account and app functionality, and your explicit consent for health data, which you give through the iOS permission prompts and can withdraw in iOS Settings.
Sharing with a friend rests on a separate consent: the invitation you send or accept, and the switch that governs passed blocks. Remove the friend or turn the switch off and the sharing stops.
Who else processes your data
Our providers are listed by role. Each operates in the United States, processes data only on our instructions, may not use it for its own purposes, and is bound by a data processing agreement with us.
| Who | Purpose | What it receives |
|---|---|---|
| Our sign-in provider | Sign-in and account security | Email address, name, and sign-in credentials |
| Our backend host | Database and file storage | Everything listed under "What Ahonui collects", including meal photos |
| A licensed nutrition database | Food search | The search terms you type when looking up a food. Sent without your name, email or account identifier. Your meal photos are not sent. |
| Our analytics provider | Counting visits to this site, and use of the app, each only if you allow it | On the site: the pages you open, how you arrived, your browser, device type and IP address. In the app: which screens you reach and where you stop, with your Ahonui account identifier and no health data |
| Apple | Sign in with Apple, and app distribution | Your Apple sign-in, handled by Apple under Apple's privacy policy |
We do not sell your personal information, and we do not share it for cross-context behavioural advertising, as those terms are used in California law.
Connected tools
You can connect AI assistants and other tools, such as Claude, to your Ahonui account. Each starts with an authorization screen where you sign in and approve that specific tool. Nothing is connected unless you approve it.
A tool you connect can read the health data on your account: meals and nutrition, fasts, water, weigh-ins, workouts, sleep, the day's movement totals, and your goals. It can log meals, water and fasts on your behalf, and, on your instruction, pause a protocol for a bounded range of days; every pause is recorded in your event history and you can end it in the app at any time. Meal photos are never available to connected tools. A connected tool cannot change which apps are blocked, cannot open a blocked app, and cannot send, spend or see a friend's pass.
A connected tool acts as your agent, on your authorization, not as our service provider, and what it does with the data you let it read is governed by that tool's own privacy policy. Everything a tool logs is marked as its work in your event history. You can disconnect a tool under Settings, then Connected tools, and it takes effect on that tool's next request.
Friends
Connecting takes both of you: one person asks and the other accepts, and nothing is shared in between. You can be found by username, which you can turn off under Settings, then Friends, after which a lookup returns nothing at all. A lookup shows the name and picture you set and nothing else. There is no directory, no search by name or email address, and lookups are rate limited.
A friend sees a short, fixed summary of your day: for each protocol, whether it was met, whether it was a rest day, whether it is paused, and how many days in a row you have kept it, plus the name and picture you set.
They do not see the numbers behind any of it: not how long you fasted, how much you drank, how far you moved, what you weigh or how you slept. They never see your meals, your meal photos, your notes, the reason you gave for pausing a protocol, or your email address. One thing is yours to add and it is off until you turn it on: with Show passed blocks on, friends also see when you walked past a block that day, which protocol was standing, and how far short of it you were. Which app it was stays unreadable, for the reason given above. Turning it on also lets those friends say one of four fixed, mildly needling lines about it, which they cannot do otherwise; a block you opened with a friend's pass is not a passed block and is never shown or spoken to. Switching it back off stops on their next refresh.
A friend who keeps every protocol they scheduled in a day can give one of their friends a pass: fifteen minutes through a block, and the day still counts toward the streak it would otherwise have ended. Giving one tells the other person your name and nothing else about your day. Using one, or having one used on your behalf when a run was about to end, records who gave it, and that name stays on the streak it held.
Friends can send you a nudge or a word of encouragement, which can appear on your block screen. They choose from a fixed set of lines Ahonui wrote and cannot write their own, and there are limits on how many they can send. Whoever sent one is told that it reached you, never at what time. Removing a friend is immediate: they stop seeing your day in the same instant, and anything either of you sent the other is deleted. Deleting your account removes you from every friend's list. Another user is not one of our service providers but a person with their own account, and what they do with what they see is not something we can control.
Where your data is held
Our backend and our providers operate in the United States. If you use Ahonui from outside the United States, your data is transferred there. Where the GDPR or UK GDPR applies, those transfers rely on the European Commission's Standard Contractual Clauses in our agreements with our providers.
How long we keep it
Day-to-day entries are kept for 400 days and then deleted automatically: meals and photos, nutrition analysis, fasts, water, weigh-ins, workouts, sleep, the day's movement totals, pauses you set on a protocol, the days Ahonui has settled, and the record of blocks you passed. Ahonui never shows more than three months of history, so nothing you can see in the app is affected by this.
A few things are kept while your account exists, because deleting them would change what Ahonui tells you about yourself: your goals and the record of when you changed them, which is what lets a past day be judged fairly rather than against goals you hold now; your streaks; your gems and the ledger they are counted from; and passes friends have given you.
Things a friend says to you are kept for 30 days. A pass a friend gave you is kept while the two of you are friends, and goes when either of you ends it.
When you delete your account we remove all of it, ahead of any of those periods: meals and photos, nutrition analysis, fasts, water, weigh-ins, workouts, sleep, movement totals, block rules and override history, your goals and settings, your streaks and gems, and your sign-in record. Deletion is immediate in the app and clears from routine backups within 30 days.
Your choices and rights
- Delete everything. Settings, then Delete account. It is permanent and needs no email to us.
- Turn off Apple Health access in iOS Settings, under Health, at any time.
- Turn off Screen Time access in Ahonui's settings. Everything is unblocked immediately.
- Disconnect a connected tool in Settings, then Connected tools. Ahonui refuses that tool's next request and every one after it.
- Get a copy, correct it, or object. Depending on where you live you may have rights of access, correction, deletion, portability, restriction and objection, and the right to complain to your data protection authority. Write to privacy@ahonui.app and we will respond within 30 days.
We will not treat you differently for exercising any of these rights.
Security
Traffic between the app and our backend is encrypted in transit, and data is encrypted at rest by our providers. Our backend identifies you from your verified sign-in on every request; the app cannot claim to be someone else.
The friends feature above is the only way one account can read anything belonging to another, and it stops the instant either of you removes the other. Nothing else in Ahonui crosses between accounts. No system is perfect.
Children
Ahonui is not directed to children under 13, and we do not knowingly collect their data. If you believe a child has created an account, write to privacy@ahonui.app and we will delete it.
Changes to this policy
If this policy changes in a way that matters, we will update the date at the top and tell you in the app before the change takes effect.
