Best Period Tracker Apps for Android in 2026

5 period tracker apps evaluated for Android users, covering Google Health Connect integration, notification privacy, and what Android's open ecosystem means for data exposure.

Android-specific considerations for period trackers include whether the app integrates with Google Health Connect (and what that means for data exposure), notification privacy on the lock screen, and whether the app's SDK bundle includes advertising or analytics libraries that can be audited. Privacy-first options (Floriva, Drip) do not integrate with Google Health Connect by design. Apps with larger feature sets (Clue, Natural Cycles) use Google's health platform but offer varying privacy protections on top of it.

Android is more flexible than iOS in a few ways. Apps can be distributed outside the Play Store, APK contents can be audited more easily, and Google Health Connect integration is optional rather than the built-in default.

That flexibility cuts both ways. Android's open SDK marketplace means many apps bundle advertising and analytics libraries that collect data beyond the app's stated purpose. For an app logging sensitive reproductive health data, checking what SDKs are included is a legitimate privacy step.

What to look for in an Android period tracker:

Google Health Connect integration. Google Health Connect (previously Google Fit) is the Android health data aggregator. Apps that sync to it send your menstrual data to Google's health infrastructure. Google's data use practices and response to legal requests are governed by US law. For period tracking post-Dobbs, this matters. Apps in this list that do not integrate: Floriva, Drip. Apps where it is optional: Clue. Apps that use it: Natural Cycles.

SDK audit. Privacy-focused apps will not include the Facebook SDK, Google Mobile Ads SDK, or major data broker analytics libraries. Floriva and Drip have been independently noted for clean SDK bundles. Flo was explicitly cited in the FTC action for sharing data via Facebook's SDK. Stardust has been verified as clean by independent reviewers.

Notification privacy. On Android, apps can show notification content on the lock screen. A reminder that reads "Your period is due tomorrow" is visible to anyone who sees the phone. Check app and Android system notification settings to control whether sensitive reminder text appears on the lock screen.

Offline functionality. Apps that require network access for core features are, by definition, sending data. Fully offline apps (Drip) or apps that work offline with optional sync (Floriva) give you control over when and whether data leaves the device.

How the options compare, at a glance.

  1. Floriva

    Paid app (no free tier)

    On-device Android period tracker. No Google Health Connect integration. No advertising SDKs. Works fully offline. Encrypted cross-device sync is opt-in.

    Strongest privacy posture for Android. The deliberate absence of Google Health Connect integration and no-ad-SDK build means menstrual data does not touch Google infrastructure unless the user chooses encrypted Floriva sync. APK size reflects the absence of advertising SDKs.

    Pros

    • Data stored on-device, does not integrate with Google Health Connect
    • No third-party advertising or analytics SDKs in the Android build
    • Notification content is configurable, sensitive reminders can be set to show minimal content on lock screen
    • Works fully without a Google account or Google Play Services for core tracking
    • No data is sent to Google's health infrastructure

    Cons

    • Paid subscription required (no free tier)
    • Smaller prediction dataset than Clue or Flo due to newer launch

  2. Clue

    Free tier / $9.99/mo

    GDPR-compliant Android period tracker, developed in Germany. Optional Google Health Connect integration. No advertising business model.

    Best privacy posture among server-based Android apps. The GDPR compliance provides stronger protection than US-based apps, and the optional (not default) Google Health Connect approach respects user choice. Be intentional about whether you enable the Health Connect integration.

    Pros

    • GDPR-compliant by default. EU privacy standards apply even to US users
    • Google Health Connect integration is optional, not automatic
    • No advertising business model; subscription-funded
    • Transparent data practices with a detailed privacy policy
    • Strong Android app quality and regular updates

    Cons

    • Server-based, data lives on Clue's servers and is subject to legal process in the EU and US
    • Google Health Connect integration, if enabled, adds Google to the data access chain

  3. Natural Cycles

    $13.99/mo or $99.99/yr (thermometer extra)

    FDA-cleared contraceptive app available on Android. Uses BBT for cycle and fertility tracking. Integrates with Google Health Connect.

    The right choice for Android users who want contraceptive-grade fertility tracking with regulatory oversight. The Google Health Connect integration is a trade-off. Consider whether you need the contraceptive functionality; if not, a non-FDA-cleared tracker with stronger privacy architecture may be a better fit.

    Pros

    • FDA-cleared as a contraceptive app, subject to regulatory oversight that pure wellness apps are not
    • BBT-based tracking provides more accurate phase and fertility identification than prediction-only apps
    • Solid Android implementation with Bluetooth thermometer integration

    Cons

    • Requires Google Health Connect or manual data entry for full functionality
    • Swedish company with data stored under EU privacy framework, but US users' data is subject to US law under some circumstances
    • Subscription plus thermometer cost is a meaningful investment
    • Designed primarily as a contraceptive tool; wellness features are secondary

  4. Stardust

    Free tier / $2.99/mo

    Period tracker with privacy-forward marketing on Android and iOS. End-to-end encrypted cycle data, no advertising SDKs, minimal data collection.

    A legitimate privacy-conscious choice for Android. End-to-end encryption is meaningfully better than unencrypted server storage. Understand the distinction: E2E encryption prevents Stardust from reading your data in plain text, but a sufficiently coercive legal process against you (not Stardust) that compels device access bypasses encryption. Good choice for most users; on-device storage is still structurally stronger for highest-risk scenarios.

    Pros

    • End-to-end encryption for cycle data
    • Privacy-centered design with explicit post-Dobbs marketing
    • No advertising SDKs in verified audits
    • Clean, polished Android interface

    Cons

    • Server-based despite encryption, the server holds encrypted data, which shifts rather than eliminates legal exposure risk
    • Smaller feature set for cycle science compared to Clue or Natural Cycles
    • Subscription required for full features

  5. Drip

    Free

    Open source, Android-only period tracker. No accounts, no server, no Google Health Connect, no analytics. Privacy claims are auditable via public source code.

    Maximum structural privacy for Android users who want verifiable claims. Open source code means you do not have to trust a privacy policy, you can read the code. No Google infrastructure touch points at all. The right choice if you want to be certain.

    Pros

    • Open source. Android users can verify the no-network-connection claim independently
    • No Google Health Connect, no Firebase, no advertising SDKs
    • Free
    • Works without Google account

    Cons

    • Android only, no iOS option
    • No cross-device sync
    • Feature set is functional but not as polished as commercial apps
    • Less active development than well-funded competitors

Quick answers to the obvious questions.

What is the best period tracker app for Android?

Clue is the strongest general-purpose Android period tracker. It has reliable cycle prediction, solid symptom logging, and GDPR protections as a German company. For privacy-first Android use, Floriva stores data on-device without Google Health Connect integration and has no advertising SDKs. Natural Cycles is the right choice if you need an FDA-cleared contraceptive algorithm. Drip is a strong open-source option for users who want source code transparency.

Is Clue safe to use on Android?

Clue is incorporated in Germany and operates under GDPR, which provides meaningful data protection for European users. Under GDPR, health data is special category data requiring explicit consent. The Swedish Data Protection Authority found issues with Clue's Facebook analytics SDK consent mechanism in 2019. Clue updated its consent process in response. Current practices are generally regarded as good by privacy researchers.

Does Flo work well on Android?

Flo's Android app is functionally strong with a large feature set. Its privacy history is the primary concern, not the Android implementation. The 2021 FTC settlement documented analytics SDK data sharing. Post-settlement, Flo updated its consent mechanisms. The app still requires an account and stores data on US servers, which creates a legal-access exposure that local-first apps avoid.

What is the most private period app for Android?

Floriva is the most privacy-forward Android option. It has no Google Health Connect integration, no advertising SDKs, on-device storage, and no required account. Drip (open source, local storage) and Euki (no account, local-first) are also strong options. None of these track cycle data on a company server, so a subpoena of the app company cannot reach your cycle history.
