Your data
Your house’s numbers are yours
What we keep, where it is kept, who can see it, and how to take it back.

Without an account, nothing leaves this device
Your answers, houses, weeks, bills, guests and photos are kept in this browser’s own storage on this device. Nothing is sent to us. A link you share from the calculator carries its answers only, never your records. Clearing the browser’s site data clears it, so keep a copy (below).

When accounts open
Accounts are optional and not open yet. When they are, if you sign in, a copy of each house you choose to keep in your account is stored with Supabase, our database provider, in a United States region: the house, its weeks and ledger, the house file (including the guests’ names and contact details you enter), receipt photos, and your email address. It travels over an encrypted connection and is stored encrypted. This device keeps its own copy and keeps working without a connection.

Who can see it
You, and the people you invite to a house: family can see and change its records; an accountant sees and changes nothing. An accountant link opens a read-only copy for whoever holds it, until the date you chose or until you turn it off. The database itself checks every request against these rules, so no one else can read your houses, including other owners. We can reach the database to keep it running, and we do not look at, sell or share your records, show you ads, or pass anything to agencies, lenders or anyone else.

What we never collect
Bank logins, card or account numbers, Social Security numbers, and guests’ payment details. Please keep them out of notes and photos too. Signing in uses a link or code sent to your email; there is no password to lose.

Take it all with you, any time
Your account and Back up both download everything as one zip: a backup you can restore, the ledger, weeks, bookings, contacts and key dates as spreadsheets, and every receipt photo. It opens without this site. No account is needed.

Delete it
On your account page, you can take a house out of your account, leave a house someone shared, or delete the account. Deleting the account removes your sign-in and every house where you are the only owner, at once. Copies in our provider’s routine backups are gone within 30 days. To clear this device, sign out and choose to remove your houses, or clear the browser’s site data.

Not advice
Shorebook organizes your numbers. It is not tax, legal or financial advice, and it never decides anything for you. Figures are estimates until your accountant confirms them.
