Red Alert — Cycle Tracker

Privacy Policy

This page explains what Red Alert does with the information you put into it, what leaves your phone, and what never does. Each section has a plain-English note beside it.

The short version

01

Who we are

The people responsible for this app and how to reach them.

Red Alert: Cycle Tracker is developed and published by Aurora Flow.

For data protection purposes, we are the data controller for the limited information described in this policy. You can contact us at any time at redalertcycle@gmail.com.

02

Tracking another person

Read this one even if you skip the rest.

Red Alert is designed for someone tracking a partner's menstrual cycle. That means you may be entering information about another person's health.

Only use this app to record someone else's cycle if that person knows about it and agrees to it. Recording another person's health information without their knowledge may be unlawful where you live, and it is not what this app is for.

We have no way to verify consent, and we do not monitor how the app is used. The responsibility is yours. Red Alert works best as something you and your partner both know about — a shared reference, not a secret one.

If someone has entered your information into this app without your agreement, you can contact us at the address in section 1 and we will help however we can — though please note that because the data lives on that person's device rather than on our servers, our ability to act is limited.

03

What the app handles

Everything the app touches, and whether it ever leaves your phone.

Green = never leaves your device. Red = leaves your device under the conditions described.

We do not ask for your name, your phone number, your address, your contacts, your photos, or your location. The app requests no location permission.

04

Where your data lives

On your phone, in the app's private storage.

Everything you enter is stored in a database and a settings file inside the app's private storage area on your device. On Android, other apps cannot read this area.

We do not operate servers that store your cycle information. There is no Red Alert account, and nothing you enter is synchronised to us.

This also means: if you uninstall the app or reset your device without a backup, your data is gone permanently and we cannot recover it.

05

Google Drive backup

Optional, off by default, encrypted before it leaves your phone.

Backup is a Premium feature and is disabled by default. If you turn it on:

  • The app packages your database and settings into a single file.
  • That file is encrypted on your device using AES-256 in GCM mode, with a key derived from your Google account address.
  • Only the encrypted file is uploaded, into a folder named RedAlertBackups in your own Google Drive.
  • The unencrypted copy is deleted from your device immediately after encryption.

The file never passes through our systems and we hold no copy of it and no key to it. Restoring a backup requires signing in with the same Google account that created it.

Be aware of what this encryption does and does not do. It protects the file against anyone who obtains it without knowing the associated account address. It is not designed to withstand a determined attacker who already knows that address. If your threat model is more serious than "I don't want a stray file readable in my Drive", do not enable backup.

Once in your Drive, the file is also governed by Google's Privacy Policy. You can delete it yourself at any time from Google Drive, and you can disable backup in the app's Settings.

Red Alert's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. We request only the drive.file scope, which grants access solely to files this app itself creates — not to the rest of your Drive.

06

Analytics

We measure crashes and general usage. Never your cycle data.

The app includes Google Analytics for Firebase, which helps us see where the app crashes, which features get used, and roughly where our users are, so we can fix problems and decide what to build.

What is sent: app version, device model, operating system version, coarse region or country, general interaction events such as opening a screen, crash and error reports, and a randomly generated app instance identifier.

What is never sent: cycle dates, phase information, daily logs, notes, intimacy records, profile names, or anything else you type into the app.

Firebase data is processed by Google. See Firebase's privacy documentation and Google's Privacy Policy. Our legal basis for this processing is our legitimate interest in maintaining and improving the app.

07

Purchases

Google Play handles payment. We never see your card.

Premium is an optional annual subscription sold through Google Play Billing. Google processes the payment and tells the app only whether an active subscription exists.

We never receive or store your payment card, billing address, or Google account password. Subscriptions renew and can be cancelled through your Google Play account settings. Payment information is governed by Google Payments' privacy notice.

08

Permissions

What the app asks for, and why.

  • Notifications — to send you a heads-up the day before a phase change. Optional; the app works without it.
  • Internet — used only for Drive backup, analytics, and verifying your subscription. Never for sending your cycle data anywhere.
  • Google account access — requested only if you enable Drive backup, and limited to files this app creates.
09

Sharing

We don't sell, rent, or trade anything.

We do not sell your information. We do not share it with advertisers, data brokers, insurers, employers, or any similar party. We do not build profiles about you and there is no advertising in the app.

The only third parties involved are the infrastructure providers named above — Google Firebase, Google Play, and Google Drive — each acting in the narrow role described in this policy.

We may disclose information if legally compelled to do so. In practice we hold almost nothing about you, so there is very little that could be disclosed.

10

Keeping and deleting data

You are in control. Here's how to remove everything.

Data you enter stays on your device until you delete it. To remove it:

  • A single day: open that day in the app and choose Clear this day.
  • A profile: delete the profile in Settings.
  • Everything on the device: uninstall the app, or clear its storage in your Android settings.
  • Your backups: delete the RedAlertBackups folder from your Google Drive.
  • Analytics: email us at the address in section 1 and we will request deletion of the analytics records associated with your app instance identifier.

Analytics records are retained by Google for a limited period and then deleted automatically. Because we hold no account for you, there is nothing else on our side to delete.

11

Your rights

GDPR, UK GDPR, LGPD, CCPA — and what they mean here.

Depending on where you live, you may have rights to access, correct, delete, restrict, or object to processing of your personal information, to data portability, and to withdraw consent.

For most of what Red Alert handles, you exercise these rights directly: the data is on your device, so you can view, change, export via backup, and delete it yourself without asking us. For analytics records, contact us at redalertcycle@gmail.com and we will respond within 30 days.

We do not sell or share personal information as those terms are defined under California law, and we do not process it for cross-context behavioural advertising. We do not discriminate against anyone for exercising their rights.

If you are in the European Economic Area or the United Kingdom, you may lodge a complaint with your local supervisory authority. If you are in Brazil, you may contact the ANPD.

12

Children

Not for under-18s.

Red Alert is not directed at children and is not intended for anyone under 18. We do not knowingly collect information from children. If you believe a child has used the app in a way that involves us holding their information, contact us and we will delete it.

13

Security

What we do, and what we can't promise.

Your data sits in the app's private storage, protected by Android's app sandbox. Backups are encrypted before upload. Network connections use TLS.

The most significant risk to your data is physical access to your unlocked phone. We recommend using a screen lock. No method of storage or transmission is completely secure, and we cannot guarantee absolute security.

14

International transfers

Analytics and backups may be processed abroad.

Google processes analytics data and Drive storage on infrastructure that may be located outside your country, including in the United States. Google applies safeguards for such transfers, including Standard Contractual Clauses where required. See Google's privacy documentation, linked above, for details.

15

Not medical advice

This is an educational tool, nothing more.

Red Alert is an educational and informational tool. It is not a medical device, not a contraceptive method, and not a fertility treatment. Its predictions are estimates based on average cycle data and will not match every person.

Do not rely on this app for contraception, conception planning, or any health decision. Consult a qualified healthcare professional for medical advice.

16

Changes to this policy

We'll date any update and flag the significant ones.

We may update this policy as the app changes. The effective date at the top of this page always reflects the current version. For changes that meaningfully affect how your information is handled, we will notify you in the app before the change takes effect.
