Privacy policy
Last updated: 7 November 2026
Sewnique is an app for tailors and dressmakers to keep their clients, measurements, orders and payments. This policy says what the app keeps, where, who else handles it, and how to have it deleted. It covers the Android app and the web app at https://sewnique.ouss.es.

The short version
- Everything you enter stays on your device unless you choose to sync it with an account.
- An account is optional. If you create one, your profile's records are kept on our server in the EU so they reach your other devices.
- The app sends no usage data or analytics anywhere.
- We don't sell your data, show ads, or share it with anyone for their own use.
What stays on your device
The app keeps each profile in its own database on your device: your business details, your clients and their measurements, orders, payments, notes and photos, and a history of the changes made to those records (the audit trail). It also keeps a technical log of what the app did, for 7 days and 5,000 entries at most, with email addresses, phone numbers, tokens and other personal data removed before anything is written. The log never leaves your device unless you share it yourself from the app's error screen, which offers its last hour.
If you turn on the app lock, your PIN is never stored. Only a salted hash of it is kept, in your device's secure storage on Android.
If you create an account
An account lets one profile sync between your devices. To make one, you give an email address and a password, or you sign in with Google.
- Your profile's records (business details, clients, measurements, orders, payments, notes, the audit trail) are stored on our server so your other devices can get them.
- Photos sync unless you turn them off in Settings › Sync.
- Your email address is used to sign you in and to confirm changes to your account. We don't send marketing email.
- Passwords are checked against known data breaches without sending them anywhere: only the first 5 characters of a scrambled copy (a SHA-1 hash) leave your device, to the Have I Been Pwned service, which can't tell which password it was.
The server is Supabase, in its EU region (Stockholm, Sweden). Records are protected so that an account can only ever read its own. To keep the service safe, requests are counted against limits by a scrambled copy of the account or the address they come from.
Your clients' data
The details you keep about your clients are yours to manage: you decide what to record and you answer to your clients for it. Sewnique keeps them on your device and, if you sync, on our server for you, and uses them for nothing else.
Sewnique never contacts your clients. When you call one or open a WhatsApp chat with them, you do it yourself, from your phone.
Who else handles your data
We use these services only to run the app, under their own data protection terms:
| Service | What for | What it receives |
|---|---|---|
| Supabase (EU) | Accounts, sync and file storage | Your account and, if you sync, your profile's records and photos |
| Resend | Sending account emails | The recipient's address and the email's content |
| "Sign in with Google", if you use it | What Google needs to sign you in | |
| Have I Been Pwned | Checking passwords against breaches | The first 5 characters of a password's SHA-1 hash |
| Vercel | Hosting this website and the web app | Ordinary web requests (IP address, browser) |
The Android app leaves your records out of Google's cloud backup, because they aren't encrypted there. Moving to a new phone with Android's own transfer brings them along.
What the app asks of your phone
The camera is used only when you take a photo.
How long data is kept
- On your device: until you delete it, delete the profile or uninstall the app.
- Trash: a deleted item can be restored for 30 days. After 90 days it is erased for good, on your devices and on the server.
- On the server: while your account exists.
- Server backups: an encrypted copy of the database is made once a week and each copy is kept for 90 days. A deleted account's data leaves the backups within 90 days.
Your choices and rights
- See and take your data: Settings › Backup exports a whole profile, or your clients, orders and payments as spreadsheets.
- Correct it: edit any record in the app.
- Delete it: delete records (they go to Trash first), delete a profile from your device, or delete your account in Settings › Account. Deleting the account erases its records and files from the server; you choose whether the profile stays on your device. https://sewnique.ouss.es/delete-account has the steps.
- Stop sync: unlink the profile in Settings › Sync.
If you live in the EU, the UK or another place with data protection law, you also have the rights that law gives you. To use them, or for any question, write to oussama.essamadi@gmail.com. You can also complain to your data protection authority.
Children
Sewnique is a work tool for adults. It is not meant for children under 16, and we don't knowingly keep their accounts.
Changes
If this policy changes, the date at the top changes too.
