Extinct — Privacy Policy
Effective date: May 2026 | Last updated: May 2026
This Privacy Policy describes how Ali3N Studios LLC (“we,” “us,” or “our”) collects, uses, and protects information in connection with the Extinct mobile application (“App”). This policy supplements our general Ali3N Studios Privacy Policy.
Extinct is a companion app for people using The Sinclair Method (TSM), a naltrexone-assisted approach to alcohol use disorder. We take the privacy of your health and recovery data extremely seriously. We do not sell your data, we do not show ads, and we do not share your personal information with third parties for marketing purposes.
1. Data We Collect
Authentication Data
The App uses Firebase Authentication. You may continue as an anonymous guest, sign in with email/password, or sign in with Google. When you sign in with Google, we receive your name (where provided), email address, and a unique user ID. This data is used solely for account management and data synchronization across devices.
Drinking Diary & Medication Logs
When you log a drinking session, the App stores the date and time, drinks recorded, units consumed, location notes you add, mood (good / neutral / difficult), naltrexone medication taken (yes/no, time, dose), and any notes you write. For signed-in accounts this data is stored in Firebase Firestore; in guest mode it is stored only on this device.
TSM Configuration
Your baseline (units per week before TSM), TSM start date, medication choice (naltrexone or nalmefene), and unit system (UK or US) are stored as user preferences. For signed-in accounts these are synced to Firestore; in guest mode they remain on-device.
Milestones & Extinction Curve Data
The App calculates compliance ratios, weekly aggregates, and extinction-curve progress from your diary entries to display your progress. These derived values are stored alongside your diary entries.
AI Consult Conversations
If you use the AI Consult feature, your messages and the AI’s responses for the current conversation are processed transiently as described in Section 2. Monthly message counts and daily conversation counts are stored as local preferences to enforce free/Pro tier limits.
Analytics & Crash Reports
We use Firebase Analytics and Firebase Crashlytics to collect anonymous usage data and crash reports. This helps us improve app stability and understand feature usage. No drinking diary content, AI consult messages, or personal recovery data is included in analytics.
2. Third-Party AI Processing
The AI Consult feature in Extinct sends your inputs to a third-party AI service. The following disclosure applies to this feature.
Who receives your data
Your inputs are transmitted to Anthropic, the operator of the Claude AI model, via Amazon Web Services (AWS) Bedrock, an AWS-hosted AI gateway. Requests are routed through our secure proxy server at api.ali3nstudios.com before reaching AWS Bedrock. Anthropic and AWS are independent third-party data processors.
What is sent
Only the inputs required for the AI Consult feature are transmitted. Specifically:
- The current conversation’s recent messages (a trimmed window of your most recent exchanges with the AI)
- A short context summary derived from your TSM configuration and recent diary entries: medication name, baseline units per week, weeks since TSM start, current week’s unit total, recent compliance ratio, and unit system. This helps the AI give responses grounded in your actual progress.
We do not transmit your name, email address, account identifier, location, device identifiers, contacts, or any data outside of the AI Consult conversation.
How your data is used
Anthropic and AWS process your inputs solely to generate the AI response that is returned to you. Your inputs are not used to train Anthropic’s models, in accordance with Anthropic’s Commercial Terms of Service and AWS Bedrock’s terms. We do not retain your inputs on our proxy server after the AI response is returned. Anthropic and AWS may retain operational logs as described in their respective privacy policies (see the Anthropic Privacy Policy and the AWS Privacy Notice).
Your explicit consent
The first time you use the AI Consult feature, the App displays an in-app consent screen that names Anthropic and AWS Bedrock, describes what data will be sent, and explains how that data will be used. No data is transmitted to the AI service unless and until you accept this consent screen. You may decline and continue using Extinct without the AI Consult feature — the Golden Rule reminders, drinking diary, extinction curve, milestones, selective extinction, and physician PDF all work without AI.
3. Data We Do NOT Collect
- We do not collect location data
- We do not collect contacts or address book data
- We do not collect health or fitness data from device sensors
- We do not collect browsing history
- We do not access your camera or photos
- We do not serve advertisements or collect advertising identifiers
- We do not track users across other apps or websites
- We do not sell any user data
4. Data Storage & Security
- All cloud data is stored in Google Firebase Firestore, which provides encryption at rest and in transit
- AI Consult requests are transmitted via HTTPS to our secure server proxy
- Guest-mode data lives only on your device in local storage (Room database and DataStore preferences) and never reaches our servers
- Diary entries in guest mode are device-bound — uninstalling the app removes them
5. Data Sharing
We share data only with:
- Anthropic (Claude AI) via AWS Bedrock — receives only the AI Consult conversation messages and the short TSM context summary described above. Sent only after you grant explicit consent. Not used to train AI models. See Section 2 for the full disclosure.
- Firebase (Google) — authentication, data storage, analytics, and crash reporting
- Google Play Billing — processes Pro subscriptions. Google handles payment data; we never see your card or billing details.
We do not share data with data brokers, advertisers, or any other third parties.
6. Data Retention
- Account data, drinking diary entries, milestones, and TSM configuration are retained while your account is active
- AI Consult request payloads are processed transiently and not stored on our server beyond the request
- You can delete individual diary entries from within the App
- Account deletion (see Section 8) removes all cloud-side data immediately
- Uninstalling the app removes all guest-mode data
7. Children’s Privacy
Extinct is designed for adults (21+ in the US, or the legal drinking age in your jurisdiction) using a physician-prescribed medication for alcohol use disorder. We do not knowingly collect information from anyone under 18. If you believe a minor has used the App, contact us and we will take appropriate action.
8. Your Rights & Account Deletion
You have the right to:
- Access your data — all data is visible within the App
- Delete your data — you can delete individual diary entries from within the App, or perform full account deletion via Settings → Delete account & data, or via this web form
- Use guest mode — if you prefer not to sync data to the cloud, the App is fully functional as a guest with all data on-device
For data deletion requests beyond what the App provides, contact us at developer@ali3nstudios.com.
9. No Advertising
Extinct does not display advertisements. We do not collect advertising identifiers. We do not participate in any advertising networks. Your recovery is not a monetization opportunity.
10. Third-Party Links
The Resources section links to external sites (TSM Options, telehealth providers, community forums). These sites are operated independently and have their own privacy policies. We do not transmit any user data to these services — tapping a link simply opens your browser.
11. Not a Medical Device or Substitute for Care
Extinct is an educational companion tool for people pursuing The Sinclair Method under a clinician’s care. The App does not provide medical advice, diagnose conditions, prescribe medication, or replace consultation with a qualified healthcare professional. Naltrexone is a prescription medication and must be obtained and supervised by a licensed clinician. The extinction-curve visualization and AI Consult responses are intended for personal reflection and do not constitute medical, psychological, or pharmacological advice.
12. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date. Continued use of the App after changes constitutes acceptance of the revised policy.
