Mytharva Privacy Policy

Last updated: July 6, 2026

Mytharva is a free single-player learning game for kids, roughly ages 10–15. We built it to collect as little about your child as possible. There are no ads, no in-app purchases, no third-party trackers, and no chat with strangers. This page explains, in plain language, exactly what we store and why.

What we collect

If your child just plays, the game runs on their device and we store nothing on our servers. Progress is only sent to us when a player creates an account or joins a Crew. In that case we store:

A display name the player chooses (this can be a nickname — it does not have to be a real name).
The hero character they picked.
Game progress: how far they've gotten and their in-game "Lumen" points across four skill areas (logic, insight, memory, and resonance).
A grade level the player selects (grades 5–10), used to pick suitable questions.
If they use a passkey to sign in, a public security key for that passkey. This is a public key only — there is no password, and we cannot use it to unlock anything on their device.

What we do not collect

We do not ask for, and do not store:

No email address
No phone number
No home or mailing address
No birthday or age
No real name (a display name is all we ever see)
No passwords
No advertising or behavioral-tracking data, and no third-party analytics

How players sign in

There are two ways to sign in, and neither uses a password:

Passkeys — the modern, secure sign-in built into phones, tablets, and computers (Face ID, Touch ID, or a device PIN). We only ever receive the public half of the key; the private half never leaves the device.
A Crew join code plus a display name — used to join a class or family leaderboard.

How we use what we store

We use the information above for two things only:

To save game progress so a player can pick up where they left off.
To show the Crew leaderboard — the display name, hero, and score of players in the same Crew.

That's it. We do not profile players, show them ads, or use their data to advertise anything.

Where it's stored

Account and progress data is stored as simple files on Mytharva's own server. It is not sold, rented, or shared with any other company, and it is not used for advertising.

Children's privacy

Mytharva is made for kids, including children under 13, so we take this seriously.

A Crew is set up by a parent or a teacher, who shares a join code with the children they're responsible for.
We do not knowingly collect anything more than a display name and game progress from a child. We never ask a child for personal contact information.
We encourage parents and teachers to play alongside their kids and to help them choose a display name that isn't their full real name.
Because there is no chat and no way to message other players, children cannot be contacted by strangers through Mytharva.

Keeping and deleting data

We keep an account's data for as long as the account is in use, so progress isn't lost between visits. You can have it deleted at any time:

Delete it yourself in the game. A signed-in account can delete its own data from within the app. (This in-app delete button is being added.)
Ask us to delete it. A parent, teacher, or player can email us and we'll remove the account's data. There's no email or real name attached to an account, so please include the display name and Crew code so we can find the right record.

No selling or sharing, no ads

We do not sell your child's data. We do not share it with advertisers or data brokers. We do not run behavioral advertising of any kind. There are no third-party trackers on the game.

Changes to this policy

If we change what we collect or how we use it, we'll update this page and change the "last updated" date at the top.
