The operating system on every iPhone, and its quiet advantage is longevity: iOS 26 still runs on an iPhone 11 released in 2019. It carries no price tag of its own because you pay for it inside the cost of the handset, and updates stay free for about seven years after that. Apple Inc. is incorporated in California, which is where the platform rules get written.

Choose Sailfish OS if…

Stick with iOS if…

- Migration costs outweigh the jurisdiction benefits for now
Why choose Sailfish OS over iOS?
The decisive argument is data jurisdiction. iOS is headquartered in the United States, 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 under EU GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and 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 jurisdiction that can change the rules without warning.
