Privacy Policy
Unlit (package com.trufchev.unlit)
Effective date: 1 November 2026
This policy explains what information the Unlit Android app ("the app") handles and why. The app is developed by Trufchev Apps ("we", "us"). You can contact us at trufchevyordan@gmail.com.
1. Your logs stay on your device
- What you enter is stored only in the app's private storage on your device. This includes what you smoke or vape, your usual amount and prices, your plan, what you log, your triggers and craving details, your if-then plans, your reasons for quitting, and your progress.
- We do not operate any servers, we do not require an account, and we never receive, read or upload this information.
- If Android backup is enabled on your device, Android may include the app's data in your device backup to your Google account. This is controlled by your device settings and governed by Google's privacy policy.
- You can erase everything at any time under Settings → Delete all data. Uninstalling the app also deletes its data from your device.
2. Advertising (Google AdMob)
The free version of the app shows banner ads, and optional rewarded ads that you choose to watch. They are provided by Google AdMob. To serve and measure ads, and to prevent fraud, the Google Mobile Ads SDK may collect and process:
- device identifiers such as the Android advertising ID,
- IP address (used to estimate general location),
- information about the device, the app, and ad interactions,
- diagnostic and performance data.
The ads SDK never receives your logs or anything else you enter in the app. Google processes this data under its own policies. See How Google uses information from sites or apps that use its services and the Google Privacy Policy.
You can reset or delete your advertising ID in your Android settings (Settings → Privacy → Ads).
3. Your consent choices (EEA, UK and Switzerland)
If you are in the European Economic Area, the United Kingdom or Switzerland, the app asks for your consent through Google's User Messaging Platform before personalised ads are shown. You can change your choice at any time in the app under Settings → Privacy & ad choices. If you do not consent, you may still see non-personalised or limited ads.
4. Purchases
Unlit Pro is a one-time in-app purchase processed by Google Play. We do not receive or store your payment details. Google Play tells the app only whether you own Pro.
5. Notifications
The optional evening check-in is scheduled locally on your device. No data is sent anywhere to deliver it.
6. Links to other websites
Settings includes links to World Health Organization pages. These open in your browser and are governed by that website's own privacy policy.
7. Health information
Unlit is a self-help tracker, not a medical device, and it does not give medical advice. For anything about your health or quitting aids, talk to a doctor or pharmacist.
8. Children
The app is intended for adults aged 18 and over. It is not directed at children, and we do not knowingly collect personal information from children.
9. Your rights
Because we do not collect or store your personal data on our side, there is nothing we hold to access, correct or delete. Your data is entirely under your control on your device. For data processed by Google for advertising, you can exercise your rights through Google using the links above. If you are in the EEA, you also have the right to complain to your local data protection authority.
10. Changes
If this policy changes, we will update this page and its effective date.
