Privacy Policy

Last updated November 9, 2026

Matlas helps grapplers find gyms, open mats and training partners. This policy explains what the Matlas app collects, why, who can see it, and how to delete it. Questions go to support.matlasgrappling@gmail.com.

What we collect

• Account: your email address and password, or the identifier Apple or Google gives us if you sign in with them. If you use Sign in with Apple and hide your email, we only see the private address Apple gives us.
• Profile: your name, username, birthday, gender, belt, About me, profile photo and home gym.
• What you post: training posts (when, where and your note), comments, direct and group messages, RSVPs, check-ins, and gyms or sessions you suggest, with any photos you add.
• Your training notes: the goals and reflections you write on the Log.
• Location: where your phone is, only while you use the app and only if you allow it. We use it for what you're doing at that moment and don't store it. A post keeps only the place you give it (see Who can see what).
• Device: a push notification token, so we can send you the notifications you turn on.
• Safety records: reports you make or that are made about you, and blocks.

Matlas has no ads, no analytics and no tracking across other companies' apps or websites.

How we use your location

We use your phone's location to show gyms and training posts near you, to put nearby places first when you search for an address, to suggest your town when you post, and to confirm you're at the gym when you check in. Each time, it's used to answer that request and then discarded. For a check-in, it's compared with the gym's location and only the time you checked in is kept. You can turn location off and still search for gyms and use the rest of the app.

Who can see what

• Everyone signed in can see your name, username, photo, belt and About me, and your training posts and their comments.
• Post locations are visible to everyone signed in. A post at a gym shows the gym. A post you host somewhere else shows the place you chose. A "looking to train" post shows your town, rounded to about a kilometer, or a pin if you chose to drop one.
• Your home gym, follower counts and lists are visible to everyone if your account is public, and only to your followers if it's private.
• RSVPs and check-ins show on a gym's Live view and in who's going to a post. If your account is private, your name shows only to people who trained at the same session and whoever is running it. Everyone else sees an unnamed athlete with a belt color.
• Messages are visible to the people in the conversation. We read them only if someone reports them or if we must to keep people safe or follow the law.
• Your birthday, gender and email address are not shown to other people.
• Your goals and reflections are visible only to you.

Who helps us run Matlas

These companies process data only to provide their service to us, under their own privacy and security commitments:

• Supabase hosts our database, photos and sign-in, in the United States.
• Google provides Google Sign-In and the map. Place search and addresses go through Google Places and Geocoding, which receive what you search for and the coordinates involved. Google's map and sign-in also collect some device and usage data under Google's own privacy policy.
• Apple provides Sign in with Apple and delivers push notifications on iPhone.
• Expo sends our push notifications to Apple and Google, including the text of the notification.
• Our email provider sends account emails such as confirmations and password reset codes.

We don't sell your personal information or share it for advertising. We may disclose information if the law requires it, or to protect someone's safety. That includes reporting child sexual abuse material to the National Center for Missing & Exploited Children.

How long we keep it, and deleting your account

We keep your information for as long as you have an account. You can delete your account at any time in the app, under Settings, Account, Delete account. If you can't get into the app, email support.matlasgrappling@gmail.com from your account's address.

Deleting your account removes your profile and photos, posts, comments, messages, goals and reflections, RSVPs, check-ins, follows and notifications right away. If you used Sign in with Apple, we also revoke our access to it. Some things are kept:

• Reports made about your account, including a copy of the words reported, without your name, to help keep people safe.
• Gyms you suggested that were approved, without your name.
• Backups, until they expire, which takes no more than a few weeks.

Your choices and rights

You can change your profile, make your account private, block people, turn off location and turn off each kind of notification in the app. You can also ask us for a copy of your information, to correct it or to delete it by emailing us. Depending on where you live, you may have further rights under laws such as the CCPA or GDPR, and you can use them the same way. We won't treat you differently for doing so.

Age

You must be at least 16 to use Matlas. We don't knowingly collect information from anyone younger, and we delete it if we learn we have. Accounts of people under 18 are private and stay private until they turn 18.

Security

Information is encrypted in transit, your session is stored encrypted on your phone, and access to your data is limited by rules enforced on our servers. No system is perfectly secure, so please use a strong password.

Changes

If we change this policy in a way that matters, we'll tell you in the app before it takes effect.
