What stays on your phone
Your food diary, trigger foods, daily guide and the foods you've matched to barcodes are stored only in your phone's web browser. We never see them. If you clear your browser's data, they're deleted.
What we keep
- Your email address and licence key – so we can send you the key and resend it if you lose it. Kept for as long as your licence is valid.
- A random code for each phone you unlock, and the date it was last used – so we can limit each key to 2 phones. It doesn't identify you or your phone's make or model.
- Internet (IP) addresses of attempts to unlock the app or resend a key – only to stop people guessing keys. Deleted after 7 days.
We use this information to provide the service you paid for (the legal basis is performing our contract with you), and to keep the service secure (our legitimate interests). We don't use it for marketing and we never sell it.
Who else is involved
- Stripe takes your payment. We never see your card details. Stripe's privacy policy: stripe.com/gb/privacy.
- Hostinger hosts this website and its database.
- Our email provider delivers your licence key email.
- Open Food Facts – when you scan a barcode, your phone asks the Open Food Facts database for that product's details. Only the barcode is sent, not your personal details.
Your rights
You can ask for a copy of the information we hold about you, ask us to correct it, or ask us to delete it (if we delete your email address, we can no longer resend your key). Email us and we'll reply within a month. If you're unhappy with how we handle your information, you can complain to the Information Commissioner's Office at ico.org.uk.
Cookies
When you unlock the app, we store one small cookie on your phone that remembers it's unlocked. It's essential for the app to work, so we don't ask for consent. We don't use any tracking or advertising cookies.
