Architecture Breakdown
Why On-Device Architecture Protects You Better
Most health apps are designed cloud-first because user data is lucrative. Ayla was engineered from scratch with a privacy-first ethos.
2. Strict Identity-Data Separation
While Ayla provides secure authentication (Email, Apple, Google) for account and subscription management, your intimate reproductive health logs and AI conversations are never linked to your profile in cloud databases.
3. Zero-Knowledge E2EE Sync
If you choose to enable cloud backups, your data is encrypted with keys that exist only on your phone hardware. Even if our servers were seized, nobody could read your records.
4. Cloud-Breach Immunity
Centralized cloud databases are prime targets for cyberattacks and subpoenas. Storing your sensitive menstrual and reproductive cycle logs locally on your hardware ensures zero server-side exposure.
Common Questions
Switching to Ayla: Privacy & Features FAQ
Why should I switch from cloud-based trackers like Flo or Clue?
Cloud-based trackers store your intimate health logs, sexual activity, and symptom history on remote corporate servers where policies can change or data can be shared with advertisers. Ayla keeps 100% of your data on your phone hardware with zero tracking.
How is Ayla's AI assistant private if other AI tools log conversations?
Mainstream AI chatbots process prompts on external cloud servers (e.g. OpenAI or cloud clusters) and may store conversation logs. Ayla's AI model runs locally on your phone's chip, meaning prompt processing and chat storage never connect to any remote server.
Can I export or backup my data if I change phones?
Yes. You can export complete unencrypted data anytime in open CSV or JSON formats. You can also use Zero-Knowledge End-to-End Encrypted backup, where only you hold the decryption key.
Is Ayla free to use?
Yes. Core period tracking, cycle history, symptom logging, pregnancy tracking, and local on-device AI are completely accessible with zero ads and zero data harvesting.
