Why choose Sailfish OS over iOS?

The decisive argument is data jurisdiction. iOS is headquartered in US, which means personal data processed through it can be subject to non-EU legal regimes — the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.

Sailfish OS removes that overhead. As a Finland-based provider, it operates natively under GDPR, and data stays inside the EU/EEA by default. For regulated sectors — health, public administration, finance — that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single non-EU jurisdiction that can change the rules without warning.

Frequently asked questions

Is Sailfish OS a good alternative to iOS?
Yes — Sailfish OS is one of the top-ranked European alternatives to iOS in our directory, covering the same security & identity use case. It is headquartered in Finland, keeping your data under EU law by default.
What's the main difference between Sailfish OS and iOS?
The biggest difference is jurisdiction: Sailfish OS is based in Finland and operates under GDPR and EU data-protection law, while iOS is headquartered in US and may transfer data outside the EU. For regulated industries or organisations following Schrems II guidance, this difference is decisive.
Is Sailfish OS GDPR-compliant?
Sailfish OS is a European company based in Finland, so GDPR compliance is the default operating model — not a bolt-on. No transfer impact assessment is required for EU customers, unlike when using iOS.
How do I migrate from iOS to Sailfish OS?
Start by exporting your data from iOS (most providers offer an export in their settings). Then import into Sailfish OS using its native import tool or migration guide. Running both in parallel for a week catches any feature or workflow gaps before you fully switch.
