Privacy Policy
1. Summary
Seizen does not collect, store, or transmit any personal data. We have no servers receiving your data, and there is nothing of yours we can see, sell, or share.
2. On-device processing
Everything you do in Seizen happens entirely on your iPhone. Your documents are processed on the device itself and never leave it: they are not uploaded to any server of ours or of any third party. When the app shows the "Processed on this iPhone" badge, it means exactly that.
3. Data we do not collect
Seizen works without asking you for anything:
- No user accounts: no sign-up, no email, no password.
- No analytics or usage metrics inside the app: it ships no analytics or tracking SDKs.
- No advertising: no ads and no advertising identifiers.
- No third-party SDKs that collect data.
4. Purchases
Seizen currently offers no in-app purchases.
5. Backups
The data you create in Seizen lives only on your device. If you have iCloud or device backup enabled, your data may be included in that backup; the backup is managed by Apple under its own privacy policy, not by us.
6. Your rights
Data protection law (such as the GDPR) grants you rights of access, rectification, and erasure. Since Seizen collects no data, there is nothing stored on any server for you to request or have deleted: all your data is on your device and under your control. If you delete the app, your data is deleted with it. For the data that is processed when you visit this site or write to us, see the next section.
7. This website and the support mailbox
Everything above describes the app. This section refers only to seizen.app, the site you are reading, which is a service separate from the app.
No cookies. This site sets no cookies and stores nothing in your browser. That is why you will not see a cookie notice: there is nothing to consent to.
Visit measurement. We use Vercel Web Analytics to see how many people visit the site and which pages they read. It uses no cookies and no persistent identifiers: each visit is recognised through a value derived from the request itself, discarded after 24 hours, which cannot reconstruct your browsing across sites or identify you. What is recorded is the page visited, the referring site, the country or region, the operating system, the browser, and the device type, always in aggregate. The legal basis is our legitimate interest (Article 6(1)(f) GDPR) in understanding how the site is used. Since nothing is stored on your device, we do not need to ask for your consent.
Server logs. The site is hosted by Vercel Inc., which, like any server, automatically records the requests it receives: IP address, browser type, timestamp, and page requested. These keep the service running and protect it from abuse, and are retained for a limited period. The legal basis is our legitimate interest (Article 6(1)(f) GDPR) in the security of the site; they are not used to identify you or to build profiles. Vercel acts as our data processor and may process these logs in the United States, covered by the EU-U.S. Data Privacy Framework and the European Commission's standard contractual clauses.
If you write to us. When you send an email to soporte@seizen.app we process your address and the content of your message for the sole purpose of replying, on the basis of our legitimate interest in handling your enquiry. We keep it for as long as the conversation lasts and a reasonable period afterwards in case you return to the same matter. We do not use it to send you marketing, and we do not share it with anyone.
Your rights over this data. You may request access, rectification, erasure, or restriction of this data, and object to its processing, by writing tosoporte@seizen.app. If you believe we have not handled your request properly, you may lodge a complaint with the Spanish Data Protection Agency (aepd.es).
8. Changes to this policy
If this policy changes, we will publish the updated version at this same address, with its revision date. If the app ever stopped working entirely on-device, we would state it here clearly before applying the change.
