Clue Integration

Stream Clue data. No Clue API needed.

Clue writes menstrual flow, ovulation tests, and cervical mucus to Apple Health’s Cycle Tracking — and Sahha’s SDK reads them into your app as normalized reproductive tags, alongside every other source.

How it works

Your users connect Clue. Sahha does the rest.

This is your user’s side of the story — one screen, once. Sahha ingests every Clue signal, normalizes, deduplicates, and delivers it to your service — raw, or as refined intelligence your product can act on.

Waiting for data…

On-device and permissioned

Clue data is read on the user’s own device, only after they grant Apple Health permission — nothing syncs without consent.

One integration, every source

Permission is per data type, not per brand. Anything that writes to Apple Health — Clue today, a new watch next year — flows through the same SDK with no extra prompt and no new code.

Data coverage

What Clue syncs through Apple Health.

Request only what you need
You choose exactly which of these signals to request from Apple Health — users are only ever prompted for those, which keeps opt-in rates high.
One schema, every source
Clue, Apple Watch, and Oura all return the same fields and units.
What crosses the bridge
Menstrual flow, ovulation tests, and cervical mucus pass through Apple Health; some app-exclusive metrics may not.

Clue writes cycle-tracking entries to Apple Health, which Sahha delivers as reproductive tags (event values like menstrual_flow: heavy) via API and webhooks. It’s an iOS app for this path — on Android, Clue exports via Clue Connect rather than Health Connect, so its data lands in Apple Health.

Sahha reads and delivers
Once permission is granted, the SDK reads Clue data from Apple Health in the background, normalizes it to one schema, and streams it to your app by webhook or API.

Start building Read the SDK docs

Most teams read live Clue data the same day they add the SDK. The only per-source prerequisite: your user has Clue’s Apple Health sync switched on — most source apps enable it by default.

Destinations

Route it into your stack.

Sahha streams every update to your webhook — and a step-by-step guide takes it the rest of the way into your database, CDP, or messaging tool.

FAQ

Clue integration questions

How does Sahha get Clue data?

Clue writes cycle-tracking entries to Apple Health, and Sahha reads them from there with its mobile SDK, delivering them as normalized reproductive tags — no Clue API to integrate.

How is cycle data delivered — as biomarkers or tags?

As reproductive tags. Cycle entries are categorical events (menstrual_flow: light/medium/heavy, ovulation_test: negative/high/positive, cervical_mucus: dry/sticky/creamy/watery/egg_white), delivered through Sahha’s API and webhooks alongside biomarkers and scores.

Does the Clue integration work on Android?

Sahha reads Clue through Apple Health on iOS. On Android, Clue exports via Clue Connect rather than Health Connect, so cover Android users through a Health Connect cycle source instead — all normalized to the same reproductive tags.

Do I need a mobile app to use the Clue integration?

Yes. Because Clue data lands in Apple Health on the user’s device, you embed the Sahha mobile SDK to read it. Cloud-only sources like Oura don’t need the SDK, but on-device sources like Clue do.

Is the Clue integration HIPAA and GDPR compliant?

Yes. Sahha is HIPAA and GDPR compliant and SOC 2 certified, and Clue data flows through the same compliant pipeline as every other source.
