Draft: to be reviewed by a lawyer
Privacy
Last updated: October 18, 2026. Plain-language note about the data we keep while families try Mastery Cove.
No ads, and we do not sell data
There are no ads. We do not sell personal information, and we do not share it for advertising.
What we keep
We keep as little as we can, in four buckets:
- Account data — a parent's email and password, plus each child's first name, grade, and province. Kept while the account is active, deleted thirty days after closure.
- Session and answer data — the practice records used for adaptive learning. Kept twenty-four months rolling, then anonymized or purged.
- AI Create drafts — stored only on the child's device. Nothing is uploaded to our servers.
- Parent dashboard metadata — one summary line per session. Same twenty-four-month window.
Homework photos
If a parent uploads a photo of homework, we use that photo once to build a practice page. Then we delete it. We do not keep a library of homework photos.
How we use it
To run the learning loop: generate questions, track mastery, send the weekly parent note, and improve content. We do not sell personal information. We do not use child data for advertising.
Who handles the data
These companies process data for us. They are not allowed to use it for their own ads.
- Supabase stores the account and practice answers.
- Cloudflare serves the website.
- Stripe is the payment processor, if a payment is added later.
- The AI provider generates question and lesson content from prompts — it does not receive child identities.
Cross-border processing
Our infrastructure providers may process data in the United States. By creating an account you consent to that processing, disclosed here.
Children under thirteen
Accounts are created and managed by a parent. Consent for a child comes from the parent, never the child. AI features for children under thirteen require the parent opt-in toggle in settings.
Classes with a teacher or tutor
A teacher or tutor can make a class and share a code. Only a signed-in parent can add their child to a class. Before joining, the parent sees the teacher's name and chooses what to share.
- Always shared with that teacher: the child's first name and grade, and practice on skills the teacher assigns, counted from the moment it is assigned.
- Shared only if the parent ticks it: skill levels from home practice, and home practice details for the last 14 days (which skills, which days, how many answers were right or missed). Never the questions or what the child typed.
- Never shared: the parent's email, the child's PIN, the parent desk, and the weekly note.
A parent can change these choices or leave a class at any time from the parent desk. The teacher stops seeing the child right away, and the child's own progress stays. We keep a record of each choice and when it was made, so we can show what a parent agreed to. That record is deleted with the child's account.
Your rights
You may request access to or deletion of your account or a child's information at any time. Email hello@masterasium.example — that address is a placeholder until the mailbox is open — or use the contact page. Every deletion request is logged with a timestamp, and we respond within thirty days.
