Privacy Policy

About this policy

This Privacy Policy explains how HabitFlow ("the app", "we", "us") handles information when you use our mobile application. HabitFlow is a habit-tracking app designed to work entirely on your device, without requiring an internet connection for its core features.

By downloading, installing, or using HabitFlow, you agree to the practices described in this policy. If you do not agree, please do not use the app.

This policy applies only to HabitFlow and does not cover any third-party websites, services, or applications that may be linked to or used within the app (such as Google Play).

Information we don't collect

HabitFlow is built to function completely offline. We do not operate any backend server for the app's core features, and as a result:

• We do not require you to create an account or sign in to use the app's core habit-tracking features.
• We do not collect your name, email address, phone number, or any other personal identifier.
• We do not access your contacts, camera, microphone, or precise location.
• We do not track your activity across other apps or websites.
• We do not run our own analytics or crash-reporting services that send data to us.

All the habits, streaks, notes, reminders, and settings you create inside the app are stored in a local database on your device only. We simply have no way of seeing this information.

Third-party services we use

While we don't collect any data ourselves, HabitFlow uses two services provided by Google to keep the app free and to offer optional paid upgrades. These services operate under Google's own privacy policy, not ours, and may process limited technical data as described below.

1. Google AdMob (Advertising)

We use Google AdMob to show banner and rewarded ads inside the app, which allows us to offer HabitFlow for free. To deliver and measure ads, AdMob may automatically collect certain technical information, such as:

This data is collected and processed by Google, not by us. You can review or opt out of personalized advertising at any time from your device settings, or read Google's own documentation for full detail.

2. Google Play Billing (Subscriptions & Purchases)

HabitFlow offers an optional Premium upgrade with monthly, yearly, and lifetime plans. All payments are processed entirely by Google Play Billing — we never see, receive, or store your card details or any other payment information.

• Google may process your purchase history, transaction ID, and subscription status to complete the purchase and confirm your entitlement to Premium features.
• Your subscription (renewal, cancellation, refund requests) is managed directly through the Google Play Store, not inside the app.
• We only receive a simple confirmation that a purchase was successful, so the app can unlock Premium features on your device.

Local data, backups & exports

Every habit, streak, note, category, and setting you create lives in a private database stored locally on your device. This data is never transmitted to us or to any third party as part of normal app use.

If HabitFlow offers a backup or export feature (for example, exporting your habit history as a CSV or PDF file), please note:

• The exported file is saved to your own device's storage, in a location you choose.
• If you choose to share, email, print, or upload that file yourself (for example, via your phone's share menu), that action — and any resulting data handling — is entirely up to you and is governed by the privacy policy of whichever app or service you shared it with.
• We do not automatically upload your backups or exports anywhere.

Permissions this app uses

Below is a plain-language explanation of the permissions HabitFlow may request, and why:

None of these permissions are used to collect, transmit, or share personal information off your device.

Children's privacy

HabitFlow is intended for a general audience and is not directed at children under the age of 13. We do not knowingly collect personal information from children, and — as explained throughout this policy — we do not collect personal information from any user at all. If you believe a child has provided personal information through a third-party service integrated into this app (such as AdMob), please contact us so we can look into it, and contact Google directly regarding their services.

Your rights & choices

Depending on where you live, you may have rights under laws such as the GDPR (Europe), UK GDPR, or CCPA (California) to access, correct, delete, or export personal data held about you.

Because HabitFlow does not collect or store any personal data on our own servers, there is generally no data for us to provide, correct, or delete on your behalf. For data processed by Google on behalf of AdMob or Google Play Billing, you can exercise your rights directly through Google:

• Ad personalization: manage or opt out anytime at adssettings.google.com.
• Account & purchase data: view or manage at myaccount.google.com and your Play Store subscriptions page.

We do not sell your personal information, and we have no personal information to sell.

Data security

Since your habit data stays on your device and is never transmitted to us, the security of that data largely depends on the security of your own device — for example, using a screen lock and keeping your operating system up to date. Data processed by Google's services (AdMob, Play Billing) is protected under Google's own security practices, described in their privacy policy.

Changes to this policy

We may update this Privacy Policy from time to time — for example, if we add a new feature that changes how data is handled. Any changes will be posted on this page with an updated "Last updated" date at the top. We encourage you to review this page periodically, and where a change is significant, we will make reasonable efforts to notify you (for example, through an in-app message or app store update notes).
