Best privacy-first iOS apps for 2026
Apple's App Privacy nutrition labels are a real signal but they're not enforcement. An app that declares 'Data Not Collected' may still ship a Mixpanel SDK that sends pageviews home - Apple's audit is shallow. The strongest signal is a small studio, an explicit privacy story, and a commitment that's checkable. Here are apps in different categories that genuinely deliver. Includes our own where they fit, plus alternatives we'd happily recommend.
What 'privacy-first' means here
- No third-party analytics. No Firebase, no Mixpanel, no Sentry on user devices.
- Local-first or iCloud-only. No vendor cloud you didn't agree to.
- Privacy nutrition label fits on one screen. Often 'Data Not Collected.'
- No required account. Or if there is one, it's optional and uses Sign in with Apple.
Notes & journaling
Bear (Shiny Frog) - local-first, optional iCloud sync, no third-party SDKs. Markdown-based, mature, beloved.
Day One (Automattic) - owned by Automattic since 2021; the app has end-to-end encryption available. Privacy posture is good if you opt-in to E2E.
Simplio Notepad (mk0.net) - our pocket notepad. Local-only, no account, no sync (by design).
Health & fitness
BodiLog (mk0.net) - our weight tracker. Writes to Apple Health only; no servers.
Habit Tracker Kit (mk0.net) - our habit tracker. Local-first, optional iCloud sync.
Streaks (Crunchy Bagel) - small studio, no analytics SDKs, iCloud sync only. A model citizen.
Productivity
Pomoly (mk0.net) - our focus timer. No accounts, local-only stats.
Pastin (mk0.net) - our clipboard manager. Clipboard history is sensitive; ours stays on-device.
Drafts (Agile Tortoise) - local-first capture tool with optional iCloud sync. Agile Tortoise (Greg Pierce) has a long-standing privacy commitment.
Reading & RSS
Simplio RSS Reader (mk0.net) - our feed reader. RSS only, no accounts, no telemetry.
Reeder 5 - long-standing iOS RSS reader, supports many sync backends or local-only mode. Indie developer, no third-party SDKs.
NetNewsWire - open source, audited, free. Genuinely privacy-respecting.
Money & business
Side Hustle Tracker (mk0.net) - our side income tracker. Local-first, no banking integrations.
Soulver - calculator-as-notebook. Local-only by design; no servers exist.
YNAB - explicitly not on this list. Cloud-based by design. Use only if you accept that.
Tools we'd avoid
Apps with 'free trial → weekly subscription' and a long privacy policy mentioning third-party advertising partners. Apps that require account creation before you can see the UI. Apps that ship Firebase Analytics or Mixpanel even if the privacy label says 'No Data Collected' - check Privacy Manifests in Xcode 15+ to verify.
If an app's privacy is important to you, the safest bet is a small studio that publishes its data flow openly. Our take on the App Store privacy nutrition label is in this post.
How to verify
Three ways to check an app's privacy story before installing:
- Read the App Store privacy section. 'Data Not Collected' is the strongest signal.
- Check the developer's website for a written privacy explanation.
- Use Apple's App Privacy Report (Settings → Privacy → App Privacy Report) after installing - it shows what every app actually contacts.
