Privacy Policy

Last updated: 23 July 2026

Sealby is designed so that there is almost nothing to collect. Your content is encrypted on your device and is never readable by us. This policy explains, in plain language, exactly what data exists around Sealby, who processes it, and what your rights are. It covers the Sealby app and the sealby.app website.

Who we are

Sealby is made by Sunset Works s.r.o., a company registered in the Czech Republic. It is the company responsible for Sealby and this website — and the one to hold to every promise on this page. Reach us at hello@sealby.app.

The short version

  • The app has no account and collects no personal data — no name, no email, no password.
  • Your files are encrypted on your device with keys we never receive. We could not read your content even if we were compelled to.
  • The app contains no analytics, no crash reporting, no advertising identifiers and no tracking code of any kind.
  • If you enable iCloud sync, your own iCloud stores only an unreadable encrypted blob.
  • This website sets no cookies and runs no trackers.
  • We have nothing to sell, rent, or lose in a breach — that is the design, not a promise.

What the app doesn’t collect

Sealby works entirely on your device. There is nothing to sign up for, so we hold no identity data. Your photos, videos, documents and notes are encrypted per file, with keys protected by your device’s Secure Enclave — they never reach us. The app sends no usage analytics and no crash reports, requests no advertising identifier, and embeds no third-party code that phones home — the only third-party code inside Sealby is open-source cryptography (such as libsodium), which never touches the network. The only network connections the app makes are ones you initiate: syncing to your own iCloud, or buying Premium through Apple.

What stays on your device, and for how long

Your vaults live only on your device (and, if you enable sync, in your own iCloud as encrypted data). Retention is entirely in your hands: deleting a file, a vault, or the app removes that data from your device; the optional duress feature wipes designated vaults deliberately. Because we never hold your content or keys, we cannot recover, disclose, or delete anything on your behalf — including for law enforcement. If you lose your PIN and a vault’s recovery phrase, that vault is gone for everyone, including us.

Encrypted backup & sync (optional, Premium)

If you enable Premium backup and sync, your vaults are stored and synced through your own iCloud account as encrypted blobs. Apple operates that storage under its own terms and privacy policy; the contents remain unreadable to Apple and to us because the keys never leave your devices. Turning sync off and removing the data from iCloud deletes those blobs; your recovery phrase stays only with you.

Purchases

Purchases are processed by Apple through the App Store using your Apple Account. We receive only the entitlement information needed to unlock Premium, verified on your device — never your name, address, or payment details. Receipts, invoices and refunds are handled by Apple under Apple’s terms.

This website

sealby.app sets no cookies and loads no tracking scripts — no advertising pixels, no third-party analytics, no fingerprinting. We see aggregate traffic statistics measured by our infrastructure provider (Cloudflare) at the network level: page counts and country-level totals, without cookies or cross-site identifiers, never tied to you as a person. Like virtually every internet service, the provider transiently processes technical data (such as IP addresses) in its logs to deliver the site and block abuse; we do not use it to identify visitors.

If you email us

If you write to hello@sealby.app, we receive your email address and whatever you include in the message. We use it only to respond, we don’t add you to any list, and we delete the correspondence when it is no longer needed.

Your rights

Privacy laws such as the GDPR give you rights to access, correct, delete, and export personal data, and to object to its processing. For your vault content the honest answer is that these rights are satisfied by design: we hold nothing about you, so there is nothing for us to hand over, correct, or erase — your data answers only to you. For the little we do process (support email), write to hello@sealby.app and we will act on it. If you are in the EU, you also have the right to complain to your data-protection authority; for us that is the Czech Office for Personal Data Protection (ÚOOÚ).

Children

Sealby is not directed at children under 13 (the minimum age in our Terms of Use, or higher where local law says so). Since the app collects no data from anyone, it collects no data from children either.

Changes to this policy

If this policy changes, the new version appears on this page with an updated date. Material changes will be called out on this website. The policy can only get more specific about how little we collect — the no-account, no-content-access design is the product, not a phase.
