No Wastes — Privacy Policy
Last updated: 28 September 2026
No Wastes helps you remember food and other products before they expire. This policy says what the app and its service keep about you, why, and how to remove it.
Who we are. No Wastes is published by Enrique Melgarejo. Contact: nowastesapp@gmail.com.
What we keep
- Your email address, to sign you in with a one-time code. There is no password.
- What you add: each product's name, quantity, expiration date, when you marked it consumed, and, if you scanned it, its barcode. The product name is free text; please do not type anything in it you would not want stored.
- Your reminder settings: how many days before, the time of day, and whether reminders are on.
- Your time zone, so reminders arrive on the right day.
- About this install of the app: an identifier the app creates itself, the app and system versions, and whether notifications are allowed. It is removed when you sign out.
- What happens to reminders: when one was scheduled, cancelled, shown, or opened, for which product, and when. We use this to learn whether reminders help. It contains no product name.
- Sign-in sessions: our sign-in provider keeps the IP address and device type of each session.
We do not collect your location, contacts, photos, or advertising identifiers, and the app contains no advertising or third-party analytics. The camera is used only while you scan a barcode; the picture stays on your phone and only the number is sent.
Barcode lookups
When you scan a barcode, we look up its product name in Open Food Facts, a public food database. We send it the barcode only, never who you are. We keep a shared list of barcodes and names that is not linked to any account.
Where it is kept
On servers in Sydney, Australia: the database and sign-in on Neon, the service on Vercel. Request logs keep the time, the address requested, and the result, never your email or your products.
The app also keeps a copy of your last product list on your phone, so it shows without a connection. It is removed when you sign out.
How long
Until you delete your account. A product you delete is kept, marked as deleted, for our counts of how the app is used, and removed with your account.
Deleting your account
In the app: Account → Delete my account. This removes your account, your products, your settings, and your reminder history on every device. It cannot be undone.
Sharing
We do not sell or share your data. The companies that host the service (Neon, Vercel) process it on our behalf only.
Changes
If this policy changes, we will update the date above and say what changed in the app's release notes.
