CycleAlign Privacy Policy

Last updated: July 2026

CycleAlign ("we", "our", "the app") is a cycle-awareness and planning app. This policy explains what information we collect, why, and the rights you have over it. We built CycleAlign to compute as much as possible directly on your device — most of your cycle predictions never touch our servers at all.

What we collect

• Account information: name, email address, and authentication data if you sign in with Google or Apple.
• Cycle data: period start/end dates, average cycle and period length — used to compute your phase predictions.
• Daily check-ins: energy level, mood, and optional notes you choose to log ("Quick Log").
• Task and calendar data: task categories you plan (never task descriptions unless you type one), and — only if you explicitly connect it — read-only access to your Google or Apple Calendar to score existing events against your cycle phase.
• AI Coach conversations: if you use "Ask Align", your questions and the coach's replies are stored to your account and used to generate contextual answers.

How we use it

Your data is used solely to power CycleAlign's features: phase predictions, task timing recommendations, personalized insights, and the AI coach. We do not sell your data, and we do not use it for third-party advertising.

Where it's processed

• On your device: cycle predictions, phase calculations, and task scoring are computed locally.
• Supabase (our backend provider): stores your account, cycle logs, and daily check-ins so you can restore your data across devices.
• Google / Apple: used only for sign-in authentication, if you choose those options.
• Anthropic (Claude): if you use the AI Coach, your question and relevant cycle context are sent to Anthropic's API to generate a response. Anthropic does not use this data to train their models under our agreement with them.

Your rights

Wherever you are, you have the right to:

• Access — request a copy of all personal data we hold about you.
• Rectification — correct inaccurate data (editable directly in-app).
• Erasure — delete your account and all associated data permanently, available directly in the app under Privacy Settings, or by contacting us.
• Portability — receive your data in a machine-readable format.
• Withdraw consent — stop any data processing at any time, including notifications and cloud sync.
• Lodge a complaint — with your local data protection authority if you believe we've fallen short.

Data retention

We retain your data for as long as your account is active. If you delete your account, your data is permanently removed from our servers within 30 days.

Children's privacy

CycleAlign is not directed at children under 13, and we do not knowingly collect data from children under 13.

Changes to this policy

We'll update the date at the top of this page if this policy changes, and notify users of material changes in-app.
