Privacy Policy

Last updated: December 25, 2025

1. Introduction

Welcome to MeSober, a lifestyle habit-tracking application designed to help you track alcohol consumption and maintain healthy habits. We are committed to protecting your privacy and being transparent about what data we collect.

Privacy-First Design: MeSober is designed with minimal data collection. We do not require user accounts, do not collect personal information like names or emails, and do not use any analytics or advertising SDKs.

2. Data We Collect

2.1 Data Stored on Your Device and iCloud

Your primary app data is stored locally on your device using Apple's SwiftData framework and can optionally sync via Apple's iCloud (CloudKit):

Data Type	Description	Storage Location
Daily alcohol units	Number of alcohol units consumed each day	Your device + iCloud (if enabled)
Personal notes	Optional notes you add to entries	Your device + iCloud (if enabled)
Entry dates	Dates of your check-ins	Your device + iCloud (if enabled)
App preferences	Notification settings, onboarding status	Your device only

            Your Control: iCloud sync is controlled by your device's iCloud settings. You can disable sync at any time in iOS Settings > [Your Name] > iCloud > Apps Using iCloud.
        

2.2 Data Stored on Our Server

We store minimal data on our server, only what is necessary for push notifications:

Data Type	Description	Purpose
APNs device token	A 64-character identifier assigned by Apple	Required to send push notifications
Timezone	Your timezone (e.g., "Europe/Madrid")	To send reminders at 9:00 AM your local time

Important: The APNs device token is not personally identifiable information. It is a random identifier that Apple assigns to your device for this app. It cannot be used to identify you, your location, or any personal details.

2.3 Data Processed but Not Stored

When you use the voice input feature:

Your voice is transcribed to text on your device using Apple's Speech framework
The text transcript is sent to our AI service (OpenAI or Groq) to extract alcohol consumption data
The extracted data (dates and unit counts) is returned to your device
The transcript is not stored on our servers - it is processed and immediately discarded

2.4 Photo Library Access

MeSober may request access to your photo library only for the optional "Sober October" feature, which allows you to:

Select a personal image to customize your progress card
Save generated progress images to your photo library for sharing

Photos are processed entirely on your device and are never uploaded to our servers.

2.5 Data We Do NOT Collect

MeSober does NOT collect:

Names, email addresses, or any personal identifiers
Precise location data (we only store timezone for notification scheduling)
Device identifiers or advertising IDs (IDFA)
Usage analytics or behavior tracking
Health data from Apple HealthKit
Contacts or other device data

3. How We Use Your Data

Push Notifications: We use your device token and timezone to send daily reminder notifications at 9:00 AM your local time
Voice Processing: We process voice transcripts through AI to help you log alcohol consumption quickly

4. Third-Party Services

We use the following third-party services:

4.1 Apple Services

Apple Push Notification Service (APNs): Delivers push notifications to your device
CloudKit: Syncs your data across your Apple devices (optional, controlled by you)
Speech Framework: Converts your voice to text on-device

4.2 AI Processing Services

OpenAI or Groq: Processes voice transcripts to extract alcohol consumption data. Transcripts are sent via secure HTTPS connection and are not stored by our server.

Please refer to OpenAI's Privacy Policy and Groq's Privacy Policy for their data handling practices.

5. International Data Transfers

Important for EU Users: When you use the voice input feature, your transcript may be processed by AI services located in the United States (OpenAI, Groq). These transfers are necessary to provide the voice extraction functionality.

We ensure appropriate safeguards for international data transfers:

All data is transmitted via encrypted HTTPS connections
Transcripts are processed in real-time and not stored
Our AI service providers maintain appropriate data protection certifications
You can avoid international transfers by using manual entry instead of voice input

6. Data Security

All communication with our server uses HTTPS encryption
Your health data (alcohol units) never leaves your device/iCloud
Server-stored data (device token, timezone) is stored in a secure database
We do not share your data with advertisers or data brokers

7. Data Retention

Device/iCloud data: Retained until you delete it or uninstall the app
Push notification token: Retained until you disable notifications, uninstall the app, or request deletion
Voice transcripts: Not retained - processed and immediately discarded

8. Your Rights Under GDPR

If you are located in the European Economic Area (EEA), you have the following rights regarding your personal data:

Right	Description	How to Exercise
Access	Know what data we have about you	Contact us via email
Rectification	Correct inaccurate data	Edit entries in the app
Erasure	Delete your personal data	Use in-app "Delete All Data" button

9. Data Deletion

Easy In-App Deletion

You can delete all your data directly from the app:

Open MeSober
Go to Settings (gear icon)
Tap "Delete All Data"
Confirm the deletion

This will delete all your local data, remove data from all iCloud-synced devices, and unregister your device from our notification server.

10. Age Requirement

This app is rated 17+ and intended for adults only.

MeSober is designed for tracking alcohol consumption, which is a regulated substance for adults. The 17+ age rating reflects:

Content related to alcohol consumption tracking
The app's purpose of helping adults monitor their drinking habits
Compliance with App Store guidelines for alcohol-related content

We do not knowingly collect data from anyone under 17 years of age. If you are a parent or guardian and believe your child has used this app, please contact us to request data deletion.
