The trade-offs of building 100% local-first iOS apps (and why I chose zero data collection)

Hi everyone! 👋

Lately, I’ve been reflecting on the architectural decisions behind indie app development, specifically the choice between Cloud Sync vs. Local-First.

When building my iOS apps, I made a strict design commitment: 100% local processing, zero user tracking, and zero data collection. While this creates instant trust and makes compliance straightforward, it also comes with real engineering trade-offs:

1. Feature Limitations: Without a central backend, cross-device sync and web-based extensions become significantly harder to implement without relying on third-party cloud tools like iCloud/CloudKit.

2. Analytics Blindspot: Operating with zero data collection means having almost no visibility into how users interact with feature flows, making UX improvements strictly reliant on direct user feedback.

For the makers and developers here:

• How do you balance user privacy against the need for product analytics and cloud convenience?

• Have you found a sweet spot for privacy-friendly telemetry, or do you prefer going completely local-first?

Would love to hear how other teams and indie makers navigate this trade-off!
