Tare — Privacy Notice
Last updated: 2026-09-06
Tare has no servers, so nothing you record is ever sent to Kalmaro. Your measurements, photos and health data stay on your device and in your own private iCloud — Kalmaro has no access to them. The app has no analytics, tracking, advertising or third-party SDKs.
No tracking, no analytics, no third-party code
Tare contains no analytics, advertising, tracking or crash-reporting services, and no third-party software libraries of any kind — it is built entirely on Apple’s own frameworks. There is no identifier Kalmaro could use to track you across apps or websites, and the app doesn’t ask for one; this is why its App Store privacy label says ‘No Data Collected’. The app talks to Apple’s iCloud to sync your own data and run competitions, and to the App Store to handle purchases. The only other request it makes is a check with the App Store for whether a newer version exists, so Settings can show an “Update” badge — that check contains nothing about you, just the app’s public App Store identifier. Nothing is ever sent to Kalmaro.
Where your data lives
Everything you record is stored on your device and synced through your own private iCloud account, using Apple’s CloudKit. That is your iCloud — Kalmaro has no access to it.
Apple Health
If you turn it on, Tare reads and writes your weight, body-fat percentage, waist circumference, BMI and lean body mass to Apple Health, and reads your date of birth, biological sex and height to help set up your profile. Health data stays between your device and your own Health app and iCloud; it is never sent to Kalmaro and is never used for advertising. Sync is off by default, and you can turn it off at any time in Settings or the Health app.
Competing with friends
When you invite people to a competition, it is shared directly between your devices using Apple’s iCloud sharing — it never passes through a Kalmaro server, and Kalmaro can’t see it. What actually leaves your device depends on how the competition is scored, and that is a difference in the data itself, not just in what the leaderboard shows. In a competition scored by improvement — the default — what is shared is your score, how much you have changed (for example ‘−1.2 kg’) and the fact that you are taking part. Your actual measurements are never written into the shared competition at all; they stay in your own private iCloud. In a competition scored by final value — including several of the ‘Fairest Picks’ quick-starts — your starting and current readings are shared with the others, because the reading itself is what decides the winner. The app tells you which kind you are creating, and warns you before you join one. Your name and profile photo are shared too, if you have set them. You are identified only by an opaque identifier that iCloud generates for this app — never your Apple ID, email address or phone number. If you’d rather not share a measurement with a particular group, don’t enter a value-scored competition on that metric with them.
Public invite links
A competition can also be joined by anyone with its link, instead of by named invite. If the host turns that on, anyone who has the link can join without their approval — and everyone in the competition, including people you never personally invited, can see each participant’s name, profile photo and progress, and can change or delete data in that competition. This is a consequence of how Apple’s iCloud sharing works, not a Kalmaro choice: the app tells you this before you join a link-based competition. The host can also turn the public link on for a competition you’ve already joined, at any point after you joined it. The host can turn the link back off at any time, which stops new people joining, though anyone who already joined stays unless the host removes them individually.
Contacts
When you invite a friend, contact search happens entirely on your device. Your contacts are never uploaded. Only the single phone number or email address you pick is sent to Apple’s iCloud, in order to invite that person.
Camera
Tare asks for camera access only when you tap the camera button, to take a progress photo of yourself so you can see how your body shape changes over time. Nothing else uses the camera. The photo is treated the same as any other progress photo — see below.
Photos
Progress photos are stored on your device and in your own private iCloud. Tare can only add photos to your library — for example when you export a picture — and cannot read your existing photo library. Photos are never uploaded to Kalmaro.
Apple Watch
If you use the Apple Watch companion, values you log move between the watch and your paired iPhone over Apple’s direct device-to-device link (WatchConnectivity). That stays between your own devices — there is no network request and no server involved.
Purchases
Tare Pro is available as a monthly subscription, an annual subscription, or a one-time lifetime purchase, all handled entirely by Apple through the App Store (StoreKit). Kalmaro never sees or receives your payment details — the app is only told whether an active purchase exists.
Support
If you email Kalmaro for support, that message and its contents are kept only in order to reply to you.
‘No Data Collected’
Tare's App Store privacy label is ‘No Data Collected’, and that is accurate. If you have any questions about privacy, see the main privacy policy, which carries the contact address.
