Privacy Policy

Last updated: June 6, 2026

The short version: Darling is private by design. The things you track — your journal, cravings, mood, quit date, smoking habits, and cycle information — are stored only on your device. We don't run accounts, we don't show ads, and we don't use third-party analytics or tracking.

This Privacy Policy explains how the Darling mobile app ("Darling", "we", "us") handles information. By using Darling, you agree to this policy.

1. Information stored on your device

Darling stores the following locally on your phone so the app can work. This information is not transmitted to us or any server:

Profile: your name or nickname, quit date and time, and notification preferences.
Smoking habits: cigarettes per day and pack cost, used to calculate money and time saved.
Cycle information: your last period date and average cycle length, if you choose to enter or sync them.
Journal & cravings: entries, moods, craving intensity, and notes you log.

This data lives in the app's local database. Deleting the app, or using Log out in Settings, removes it from your device.

2. Health Connect (optional)

If you choose to enable cycle syncing, Darling requests permission to use Android Health Connect:

Read: your most recent menstrual period date, used to determine your current cycle phase.
Write: a mindfulness/exercise session when you complete a Craving SOS breathing exercise.

Health Connect data is used only on your device to power cycle-aware features. It is never sent to us, never shared with third parties, and never used for advertising. You can grant or revoke these permissions at any time in Settings or in the Health Connect app. Using Health Connect is entirely optional — you can also enter your last period date manually, or skip cycle features altogether.

3. Subscriptions and payments

Darling offers an optional premium subscription processed through Google Play Billing. Google handles the transaction and your payment details — we never see or store your payment information. We only receive your subscription status (active or not) so the app can unlock premium features. Google's handling of your purchase is governed by the Google Privacy Policy.

4. Notifications

If you enable notifications, Darling schedules reminders (milestone celebrations, daily encouragement, and gentle cycle nudges) locally on your device. These are generated on-device and not sent through our servers.

5. What we do not do

We do not require an account or collect your email to use the app.
We do not show ads.
We do not use third-party analytics, advertising, or tracking SDKs.
We do not sell, rent, or share your personal information.

A community leaderboard is not active in the app. If we introduce it in the future, it will be strictly opt-in and clearly described before any information is shared.

6. Children

Darling is intended for adults (18+) who are quitting smoking. It is not directed to children, and we do not knowingly collect information from anyone under 18.

7. Data retention & deletion

Because your data is stored on your device, you are in control of it. To delete everything, use Log out in Settings or uninstall the app. To manage Health Connect data, use the Health Connect app on your phone.

8. Security

Your information stays within the app's private storage on your device, protected by your device's own security. No method of storage is perfectly secure, but keeping data on-device avoids the risks of transmitting and storing it elsewhere.

9. Changes to this policy

We may update this policy as the app evolves. When we do, we'll revise the "Last updated" date above and, for significant changes, provide notice in the app.
