Privacy Policy
Sesslynx is built to keep as little personal information as possible, especially about kids. This policy explains what we collect, why, and the choices you have.
Who we are
Sesslynx is a product of Xentric Labs (“we”, “us”). This policy covers the Sesslynx website, web app, and mobile apps (the “Service”).
Information we collect
Account information
- Your email address, display name, time zone, and whether you use Sesslynx as a coach, a parent, or both.
- An optional phone number, if you choose to add one.
Information about kids
- A kid's first name, and optionally a birth year and a color label used to tell kids apart in the app. We do not ask for last names, full dates of birth, photos, or school information.
- The classes they are enrolled in and their attendance records.
Class and billing records
- Classes, schedules, rate plans, policies, attendance marks, confirmations, and disputes.
- Payments you record (amount, date, and method such as Zelle, Venmo, cash, or check). We do not collect bank or card numbers for recorded payments.
Messages and family members
- Messages you send in a class chat: the text, the time it was sent, and who sent it. When a message is deleted, its text is removed and only a “Message deleted” marker remains.
- Reports you make about a chat message. A report is shared with the coach of that class.
- If you invite a co-parent, or accept an invite to be one, the link between your accounts so you both see your family's records.
Technical information
- Basic device and log data needed to run and secure the Service, and push notification tokens if you allow notifications. Push tokens are used to deliver attendance notices, reminders and class chat notifications.
How we use information
- To provide the Service: show sessions and balances, deliver class chat messages, send attendance notices, chat notifications and reminders, and produce monthly statements.
- To keep the Service secure and to prevent abuse.
- To respond to you when you contact us.
We do not sell personal information, and we do not use kids' information for advertising.
Who can see what
- A coach sees the kids, sessions, and balances in their own classes.
- A parent sees their own kids' sessions and balances. In group classes, a parent sees only their own kid's row.
- A primary parent can invite a co-parent, who then sees the same kids, balances, statements and class chats. The primary parent can remove a co-parent, and a co-parent can leave, at any time.
- Class chat messages are shown to the class's coach and the families enrolled in it. Your name is shown with your messages; other families' kids' names are not shown.
- We use service providers (for example, hosting, database, and email delivery) who process data on our behalf under contract.
Children's privacy
Accounts are for adults: coaches and parents or guardians. Kids do not have accounts. A parent or coach adds a kid's first name to a class. Parents can edit or remove a kid in the app at any time, or delete their account, which removes their kids' names and birth years (see how deletion works). Parents can also ask us to review their kid's information.
Retention
We keep records while your account is active so both sides have an accurate history.
Deleting your account
You can delete your account in the app at Settings → Delete account, on the web or on your phone. You can also follow the steps at sesslynx.com/delete-account.
- Deleting removes your name, email and phone number, your kids' names and birth years, the text of your chat messages, your push tokens, and your notifications and preferences.
- It ends your links with coaches or families and your classes, and locks your sign-in immediately.
- Session, payment and ledger records shared with the other side are kept without your name, because they are also the coach's or family's financial history.
Your choices
- Access, correct or export your information from your account settings or by contacting us, and delete your account at Settings → Delete account (see how deletion works).
- Control email and push notifications in your settings.
Changes
We will post changes to this page and update the date above. For significant changes, we will notify you in the app or by email.
