The short version: Spell & Sum is bought by a parent, for their own children, and stores about as little as a service like this can. There are no ads, no cross-site tracking, and nothing here is sold.
Children do not have accounts
You hold the account. Children never sign in, and we never knowingly collect personal information from a child. A “child profile” is a label you type so you can tell your own saved settings apart, and it holds exactly two things:
- A display name — whatever you type. It does not have to be their real name.
- A grade band, optionally.
No birthday, no school, no email address, no photograph, no scores, no location. Those fields do not exist in our database, so there is nothing to leak, subpoena or sell.
What we store about you
- Your email address, so you can sign in and we can email you about your subscription.
- Your time zone, so “three sheets this week” means your week, not ours.
- The worksheet settings you save, and a record of sheets you printed.
- If you subscribe, a customer and subscription id from Stripe. Card details go to Stripe directly and never reach our servers.
Worksheets themselves are not stored as files. We keep the settings and a number used to regenerate them, which is smaller and means an old sheet can be reprinted exactly.
What we do not do
- No advertising, and no advertising networks on any page.
- No third-party analytics that follow you across other websites.
- No selling, renting or sharing of personal information. There is no market for it here.
- No profiling of children. We do not know how a child performed, because we never ask.
Cookies
One cookie, to keep you signed in. It is not used for advertising and not shared. Your browser also stores your time zone locally so we only send it once.
We email sign-in links and messages about your subscription — a reminder three days before a trial converts, and a note if a card is declined. There is no marketing list to unsubscribe from, because we do not run one.
Deleting everything
Email hello@spellandsum.com and ask. Your account, children, saved settings and history are deleted, not anonymised and kept. Stripe retains payment records for as long as tax law requires, which is out of our hands.
Where the data lives
On servers in the United States, with Stripe as the payment processor and a transactional email provider for the messages above. That is the entire list of companies your data touches.
Changes
If this policy changes in a way that affects what we collect, account holders get an email — not a quietly edited page.
