Privacy policy
Kyntra is a workout log. We keep what it needs to back up your workouts and to help you find your gym, and nothing to sell or to track you.
Who we are
Kyntra is run by Christopher Simonson, doing business as Meridion Systems, who is responsible for the data described here. Mail: 4631 W Midway Ave, Glendale, AZ 85301, United States. Email: support@kyntra.fit.
What we collect and why
Without an account
You can log a workout without signing in. It stays on your phone and is not sent to us. If you allow location, gym suggestions still use it as described under Location.
Your account
You sign in with Apple or Google. We keep only the account id they give us, which is how we recognize you. Their sign-in can also include your email address, and Google's includes your name and photo. We don't keep your email address, name or photo, and we never receive your Apple or Google password.
Your workouts and settings
When you are signed in, the app backs these up to your account so they are safe and can return to a new phone:
- Workouts: when they started and ended, your time zone, the gym you chose, your notes and pauses.
- Exercises and sets: weight as you typed it and its unit, reps, time, distance and effort.
- Plans, with their reminder days and time. Reminders are scheduled on your phone; we don't send push notifications.
- Exercises you create.
- Settings: your weight unit and the "Still training?" prompt. Your language choice stays on your phone.
Your workouts are private. Other people can't see them.
Gyms you add
When you add a gym, we keep its name, address and country, and the position where you were when you added it. A gym is public when it can be confirmed as a real gym at that spot; then everyone can see its name, address and position, but not who added it. A gym that can't be confirmed stays visible only to you.
We also keep, linked to your account, other names you suggest for a gym, equipment you add, and reports you send about a gym or a machine (for example that it has closed). Others see the names and equipment, never who added them. Reports are seen only by us.
Keeping the service running
- Daily counts of some actions, such as gym checks and backups, linked to your account, so the limits that protect the service can work.
- Your sign-in session, so you stay signed in. We keep only a scrambled form of its key.
- Server logs of requests, such as the path requested, the result and how long it took. They don't contain your location, workouts, tokens or email.
- Your IP address is used briefly to limit repeated requests. We don't store it.
When you contact us
If you email us, for example with Send feedback in the app's Settings, we receive your email address and what you write, and use them only to answer you. The feedback mail starts with the app version, your phone's system and version, and the app language, so we can look into a problem. You can delete any of it before you send.
Crash reports
Kyntra doesn't send crash reports yet. We plan to use Sentry for them. When we do, this policy will say what they contain.
Location
- Kyntra asks for your location when you start a workout, and only while you use the app. It never uses location in the background.
- It is used to suggest the gym you are at. Once you have allowed it, the app also uses it when you choose or add a gym.
- Your position is sent to our server to find gyms near you. To ask Google for gyms, our server sends only the center of an area of about 1 km around you, not your position.
- When you add a gym, the address form can be filled in from your position using your phone's built-in map service (Apple on iPhone, Google on Android). To confirm a new gym, our server sends its name, address and position to Google.
- We don't store your location, except as the position of a gym you add.
- You can always choose or add a gym by hand. Kyntra works fully without location.
Ads
Kyntra shows no ads in this version. If we show ads later, they will come from Google AdMob and will be non-personalized: they are not based on your activity in other apps or on your profile. Where the law requires it, for example in the European Economic Area and the United Kingdom, Google's consent form will ask for your choice first, and you can change it at any time in Settings, Ads, Ad privacy choices.
What we don't collect
- We don't sell your data or share it for advertising.
- We don't track you across other apps or websites, and we don't use your device's advertising identifier.
- No contacts, microphone, photos or health data.
- Kyntra doesn't use your camera in this version.
- No analytics tools.

How long we keep it
| Data | How long |
|---|---|
| Your account, workouts, plans, exercises and settings | Until you delete your account |
| Workouts, plans or exercises you delete | Marked as deleted so your other devices remove them too, then removed with your account |

Your choices and rights
- Export your data: in the app, go to Settings, Account, Export my data. You get a file with your account, workouts, plans, the exercises you created, settings, and the gyms, names, equipment and reports you added.
- Delete your account: in the app, go to Settings, Account, Delete account. This deletes your account, workouts, plans, settings, sign-in, reports and the gyms only you can see, from our servers and from your phone. Public gyms, gym names and equipment you added stay for other people, without your name. If you used Sign in with Apple, we also ask Apple to remove Kyntra's access.
- Location: you can turn it off in your phone's settings at any time.
- Anything else: email support@kyntra.fit. Depending on where you live, you may have the right to access, correct, delete or move your data, and to object to or limit how we use it. You can also complain to your data protection authority.
We use your data to provide the service you asked for (backing up workouts, finding gyms), for our legitimate interest in keeping the service secure and the shared gym list accurate, and, for ads where the law requires it, with your consent.
Children
Kyntra is not for children under 13, or under 16 in the European Economic Area and the United Kingdom. If you think a child has given us data, contact us and we will delete it.
Changes to this policy
When we change this policy, we will post the new version here with a new effective date. If a change affects how we use your data, we will tell you before it applies.
