Privacy Policy

What Serifu collects, why, and who processes it.

Serifu is operated by Peter, an individual ("we"), who is the data controller under the EU General Data Protection Regulation (GDPR). For anything about your data, email support@serifu.net.

Your files

Your manga files stay on your computer. When you translate a page, the page image (and crops of its text regions) is sent to our servers only for that request, passed to the AI providers below, and not stored afterwards, including pages refused by the safety checks in our Acceptable Use Policy. We do not use your pages to train models.

Translating on serifu.net in the background (the default there): the pages you choose are uploaded and kept on our servers while they are translated and for 24 hours after the run ends, then deleted; a page refused by the safety checks is deleted at once. You can delete them sooner with Remove. Choose Only in this browser when you start, and pages are sent only for each request and not stored, as above. When a background run ends, we email you at your account's address.

What we collect

  • Account: email address, name, and, if you sign in with Google, your Google account ID and profile picture.
  • Credits: your balance and a ledger of grants, purchases, pages used and refunds.
  • Linked computers: for each signed-in app or browser, the time it signed in, its user agent (for example Serifu/0.1.0 (Windows)) and IP address.
  • Payments: Waffo processes payments as merchant of record. We receive the order ID, amount and your email; we never see card details.
  • Support: messages you send us.
  • Visits, only if you allow it: pages viewed and the site that sent you, through Google Analytics and PVUV, and the page your first visit started on, saved with your account if you create one.
  • Use of serifu.net, while signed in: when you start a translation and how it ended, the number of pages in a file you open, and the steps toward buying credits (the prompt to buy, the pack you choose, the checkout opening). Kept three months, to see where the site fails readers; no file names and no pages.

Why

To run your account, translate your pages, charge and refund credits, prevent abuse, and answer support requests.

Who processes data for us

We use carefully selected service providers, bound by data processing agreements, only for the purposes below:

  • Hosting and infrastructure: running the website, database and email delivery.
  • Payments: a merchant of record that handles payment, taxes and receipts.
  • AI processing: models that segment, read and translate pages and clean artwork, and a content moderation service that checks pages and results for prohibited content.
  • Sign-in: Google, only if you choose to sign in with Google.
  • Newsletter: an email service, only if you subscribe.
  • Visit counts: Google Analytics and PVUV, only if you allow it on the cookie bar.

They may only use your data to provide these services to us. Some are located outside the EU; where that is the case, transfers are covered by the European Commission's standard contractual clauses or an adequacy decision. Ask support@serifu.net for the current list of providers.

The iOS app

  • Free translation reads and translates pages on your phone: nothing is uploaded.
  • Paid translation sends a page to our servers as described under Your files, only when you choose it, and it is not stored.
  • Sign in with Apple: we receive an identifier for your Apple account and, if you choose to share them, your name and email address (which may be a private relay address from Apple).
  • Purchases in the app are processed by Apple. We receive the transaction ID, the product and its price, and a random identifier that ties the purchase to your Serifu account; we never see your payment details. If Apple refunds a purchase, it tells us, and we remove its credits.
  • Delete your account in the app's Settings: the account, its credits and its purchases are removed as described under Retention.

Retention

Account and credit records are kept while your account exists. Deleting your account removes them, except records we must keep for tax and accounting. Page images are not retained. Pages translated in the background on serifu.net are deleted 24 hours after their run ends.

Your rights

Under the GDPR you can access, correct, export or delete your data, object to or restrict its processing, and withdraw consent. Delete your account from Settings, or email support@serifu.net; we reply within 30 days. You can also complain to the data protection authority in your EU country.

We process account, credit and payment data to provide the service you signed up for (contract), and sign-in and abuse-prevention data for our legitimate interest in keeping Serifu secure.

Visit counting is based on your consent, which you can withdraw any time with Cookie settings at the bottom of every page.

Cookies

We use cookies needed to keep you signed in and remember your choices and, only if you allow it, cookies that count visits. See the Cookie Policy.
