Behave or Misbehave — Privacy Policy

Who we are

Behave or Misbehave (“Behave”) is published by DOKU YAPAY ZEKA YAZILIM TEKNOLOJİ LİMİTED ŞİRKETİ (“Doku Labs”, “we”), Caferağa Mah. Şifa Sk. No: 19, 34710 Kadıköy/İstanbul, Türkiye. Behave is a personal habit journal: you record whether a day went well, optionally tag what went wrong or what you did better than usual, and the app shows you streaks, fasting timers and periodic reports. This page explains exactly where that information goes.

The short version

Behave has no server holding your data, and no user accounts. Everything you log stays on your iPhone and, if you use iCloud, in your own private iCloud account. Figures read from Apple Health are the exception: they stay on your iPhone only. If you link with a partner in Two of us, the answers and notes you give each other there are shared with that one person through iCloud, nothing else. If you ask friends to cheer you on, each friend shares only the notes they leave you and the goal you set, the same way. We cannot read any of it, and there is no database anywhere holding your entries.

Behave does not collect, receive, transmit or store any personal data on our behalf. There is no sign-up, no login, no analytics service and no backend that the app reports to.

What you log

Your daily entries, notes, custom tags, settings and fasting sessions are written to a database file inside the app’s private storage on your device. The letter you may write to yourself, and any photos you choose for your stickers or your letter, are kept in the same private storage. From version 1.6 so are your goals: the sets you begin, the balls you move into the hourglass, and a history of your run/walk sessions (when each began, its plan, the rounds and active minutes). Photos reach Behave only through Apple’s photo picker, and only the ones you pick. Deleting the app removes all of it from the device.

Apple Health

If you grant permission, Behave reads the following from Apple Health so it can show them beside your entries and suggest, never automatically record, bonuses: steps, walking and running distance, exercise minutes, workouts, heart rate, resting heart rate, VO₂ max, sleep, body weight, and active and resting energy.

Behave writes one thing to Health, and only if you ask it to. From version 1.5, when you start a run/walk interval session with the voice turned on, the app asks once for permission to save workouts. If you allow it, the session runs as a walking workout and is saved to Health when it ends: its start and end time, duration, and the distance and active energy your iPhone measured during it, and from version 1.7 the route you walked (see Location below). With the Behave app on an Apple Watch, the Watch records the session instead and saves it with the heart rate and active energy it measured. A session stopped within its first minute is discarded rather than saved. Behave writes nothing else to Health, and never changes or deletes anything already there. If you decline, the intervals still work; you can change the answer in the Health app under Sharing → Apps → Behave.

Health data read by Behave is stored only on your iPhone. Unlike the rest of your log, it is never copied to iCloud: from version 1.5 it is kept in a file on the device that is also excluded from iCloud backups, and a new iPhone reads it back from Health itself. A workout Behave saves lives in Health like any other. Health data is never used for advertising or marketing, never sold, never shared with any third party, and never used for any purpose other than showing you your own information inside the app. You can withdraw access at any time in the Health app under Sources, or in iOS Settings under Privacy & Security → Health.

iCloud

If you are signed in to iCloud, Behave mirrors your log (what you log yourself, not the figures it reads from Apple Health) into the private database of your iCloud account, using Apple’s CloudKit; from version 1.4 also your stickers, your letter (its words and photos) and your settings, so that reinstalling the app or moving to a new iPhone brings them back. The same goes for any trips you mark: those are start and end dates only. From version 1.6 your goals and your run/walk session history are mirrored the same way (from 1.6.1 with the day you first opened Goals, where your stock begins); the daily step totals Goals counts come from Apple Health, so like every Health figure they stay on your iPhone. Your location is never part of it: Behave reads it only during a run/walk session you start (see Location below), and a trip is dates only, never a place. A private CloudKit database is accessible only to the Apple Account that owns it; we have no access to it and receive no copy. Apple handles that data under Apple’s Privacy Policy ↗.

You can stop this at any time by turning iCloud off for Behave in iOS Settings, and you can delete the stored copy under Settings → your name → iCloud → Manage Account Storage. The app keeps working as a local-only journal either way.

Two of us (sharing with one partner)

From version 1.8, Behave has an optional feature, Two of us, behind the heart on the Today screen. Nothing is shared until you use it. You invite one person: iCloud creates a single-use link, and you send it through whichever app you choose in the iOS share sheet; Behave sends nothing itself. When your partner opens the link in Behave on their iPhone, the two of you share one small space in iCloud, using Apple’s CloudKit sharing.

Only the answers given inside Two of us are in that space: for each evening, the answers one of you picked about the other from a fixed list of kind answers (whether the other made your evening easier, whether they helped at home, and one kind thing they did; there is no free text), with the date they are about, when they were given, and an identifier iCloud assigns to each account. Each of you sees the other’s first name as iCloud provides it. Nothing else from your log is shared: not your verdicts, slips, bonuses, evening notes, symptoms, weight, Apple Health figures, fasts, sessions, goals, letter or stickers. Two of us never changes your verdict.

From version 1.9, either of you can also leave the other a note: words you write and, if you choose, one photo you pick and up to a minute of your voice. You choose when it opens (on a hard day in the other’s log, or after a run of good days), and until then the other sees only that a sealed note is waiting, when it will open, and whether it holds words, a photo or a voice. A note, its photo and its recording are kept in the same shared space in iCloud as the answers, with a copy on each of your iPhones (the photo and the recording outside the device backup). When a note opens, the reader’s iPhone records when, so the writer can see that it was opened. Either of you can delete a note at any time, which removes it from both phones. Behave asks for the microphone only when you press Record, and records only while you do; the photo comes through Apple’s photo picker, which shows Behave only the photo you pick.

The space lives in the iCloud account of the person who sent the invite, and only the two of you can read it; we have no access to it and receive no copy. Either of you can leave at any time from the same screen: when the inviter leaves, the whole space is deleted; when the invited person leaves, their answers and notes are deleted first and their access ends. When your partner answers or leaves you a note, iCloud lets your iPhone know through Apple’s push notification service (that signal carries none of it), and Behave shows a notification it makes on your iPhone (for answers, only if you turned on Tell me when they answer). A notification never contains what was said or written.

Cheer squad (notes from friends)

From version 1.10, Behave has an optional cheer squad, behind the flexed arm on the Today screen. Nothing is shared until you use it. You set a goal (a number of good days in a row, with a line in your own words if you like) and invite friends one at a time: for each friend iCloud creates a single-use link, which you send through whichever app you choose in the iOS share sheet; Behave sends nothing itself. Each friend who opens their link in Behave on their iPhone shares one small space with you in iCloud, using Apple’s CloudKit sharing, and each friend has a space of their own: friends never see each other, or each other’s notes.

A friend’s space holds only the goal (how many days, the line you wrote, the day it began) and the notes that friend leaves you: words, and if they choose one photo they pick and up to a minute of their voice, at most two per friend. You see that a note is waiting, as a sealed envelope, but not what it says until you open it: one becomes ready every few good days in a row, the rest when you reach the goal, and one early on a hard day; ready notes wait for you, and you open one a day. When you open a note, your iPhone records when, so your friend can see that it was opened, not why. Each of you sees the other’s first name as iCloud provides it. Nothing from your log is shared: not your verdicts, slips, bonuses, progress, evening notes, symptoms, weight, Apple Health figures, fasts, sessions, goals, letter or stickers.

The spaces live in your iCloud account, and only you and that friend can read each one; we have no access and receive no copy. Notes, their photos and recordings are kept there, with a copy on each of your iPhones (photos and recordings outside the device backup). You can remove a friend at any time, which deletes their space and their notes and ends their link; ending the challenge does this for every friend. A friend can stop cheering at any time, which deletes their notes from both phones. When a friend leaves you a note, or you open one of theirs, iCloud lets the other iPhone know through Apple’s push notification service (that signal carries none of it), and Behave shows a notification it makes on the iPhone. A notification never contains what was written. As in Two of us, Behave asks for the microphone only while a note is being recorded, and photos come through Apple’s photo picker.

Location (run/walk sessions)

From version 1.7, when you start a run/walk interval session, Behave asks once for permission to use your location while using the app. While that session runs, and at no other time, it uses your location to measure the distance and the pace of the segment you are in, shown in the app, on your Lock Screen and on your Apple Watch, and to save the route you walked to Apple Health with the walk. Running in your pocket, it keeps the voice coach awake, which is why iOS shows the blue location indicator during a session. From version 1.7.1, when your Apple Watch records the session (for example one you started on the Watch with your iPhone in a pocket, where iOS does not let the iPhone start location), the Watch asks once for its own permission and measures the session with its GPS instead, for the same purposes; its points go only to your iPhone, for the summary, and into your own Health. Location stops when the session ends.

For the session’s summary, Behave keeps a simplified sketch of the route, the distance and the split times on your iPhone only, outside iCloud and outside your device backup, and deletes them with the session. Your location is never copied to iCloud and never sent to us or to anyone else; the full route goes only into your own Health. If you decline, the intervals still work, without distance or route, and the changes arrive as notification chimes instead of the voice. You can change the answer in iOS Settings → Behave → Location.

Motion & Fitness (free runs)

From version 1.7.1, when you start a run/walk session, Behave asks once for permission to read Motion & Fitness. It uses it for one thing: during a free run, it reads your step rate from your iPhone’s motion sensor to tell running from walking, so the free run ends by itself when you slow to a walk. It is read only while a free run is on, kept in memory for at most three minutes, and never stored, copied to iCloud or sent anywhere. If you decline, a free run is judged more cautiously by your speed during the session, or you end it yourself. You can change the answer in iOS Settings → Behave → Motion & Fitness.

Apple Watch

From version 1.7, Behave has an Apple Watch app for run/walk sessions. During a session it reads your heart rate and active energy from the Watch’s sensors to show them on your wrist, and saves the session to Apple Health as a walk (see Apple Health above). Your iPhone and your Watch talk to each other directly through Apple’s WatchConnectivity (the session’s plan, pause and stop, and the distance your iPhone measured) with no server in between.

Goals: the motion sensor and sharing

From version 1.6, while the Goals screen is open, Behave reads your iPhone’s motion sensor so the balls in the hourglass, and the medals in your medal box, roll when you tilt the phone. Only the tilt is used, only while that screen is showing, and nothing is recorded or sent anywhere; iOS asks no permission for this because no motion history is involved.

You can share a set as a short video. It is made on your iPhone, played back to you before anything is sent, and leaves the phone only through the iOS share sheet, to the app or person you choose; Behave uploads nothing and we receive no copy. The video shows the set’s name, its dates, counts of days and the hourglass; it never contains a slip, a note, your weight, a symptom, your letter, a sticker or anything from the report. The file is deleted from the phone when you close the share screen.

On-device intelligence

On iPhones that support Apple Intelligence, the wording of the weekly and monthly report may be drafted by Apple’s on-device language model. This runs entirely on your iPhone. Nothing is sent to Apple, to us, or to any other service, and no third-party AI provider is involved.

Notifications and the interval voice

The optional nightly reminder and the run/walk interval chimes are local notifications scheduled by your iPhone. No push server is involved and no notification content leaves your device; the exceptions are Two of us and the cheer squad (see above), where iCloud wakes the app through Apple’s push service when your partner answers or someone leaves or opens a note. The spoken interval cues are generated on your iPhone by Apple’s built-in speech synthesizer and played by the app itself; nothing is recorded and nothing is sent anywhere. From version 1.7 the countdown on your Lock Screen is a Live Activity, drawn and updated by your iPhone itself; no push server is involved.

From version 1.7, the session summary shows the heart rate, active energy and steps Apple Health holds for the session’s time; they are read when you open the summary and never stored by Behave. The monthly recap is worked out on your iPhone from your own log. Sharing one of its slides makes an image on your phone and hands it to the iOS share sheet; Behave sends nothing itself, and slides about slips, drinking, symptoms, weight or your notes cannot be shared. When the app asks for an App Store rating, it uses Apple’s own rating prompt.

Our other apps

At the foot of the report screen Behave lists our other apps, and at launch it checks whether a newer version of Behave is available. For this the app fetches a small public file from GitHub and asks Apple’s public iTunes lookup service which apps are actually on the App Store. Those two services receive standard network information such as your IP address; they receive no identifier for you and no part of your log. Tapping an entry opens the App Store. No advertising SDK is involved, nothing is measured, and nothing about you is sent anywhere.

Advertising, analytics and tracking

Behave carries no third-party advertising, no advertising SDK, and no analytics, attribution or crash-reporting SDK such as Firebase, Tenjin, Adjust or AppsFlyer. The only promotion in the app is our own list of apps described above. Behave does not track your activity across other companies’ apps or websites and does not show an App Tracking Transparency prompt.

Your data, exported

Behave can export your complete log as a JSON or CSV file that you save wherever you choose. The export is produced on your device and sent nowhere; it exists so your record remains readable without this app.

Children

Behave is not directed at children under 13, and we do not knowingly collect personal information from children, or indeed from anyone.

Your rights

Under the Turkish Personal Data Protection Law No. 6698 (KVKK) and, for users in the EU and UK, the GDPR, you may ask us whether we process your personal data, and ask for access, correction or deletion. Because Behave sends nothing to us, we hold no personal data from the app; your log is under your control on your device and in your iCloud, as described above. You can still write to us at [email protected], and we will answer within 30 days.

Changes to this policy

We will update this page, with a new date, before any change to what leaves your device ships in the app.

Support and contact

If something is broken, confusing or missing, write to [email protected] and describe what you were doing when it happened. Because we collect no data, we can only work from what you tell us.
