Privacy Policy

Last updated: December 25, 2025

Please read this agreement carefully, as it contains important information regarding your legal rights and remedies.

Introduction

Twik ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our Android and iOS applications, including the Android accessibility overlay and the iOS keyboard extension (collectively, the "App"). By using the App, you agree to the collection and use of information in accordance with this policy.

Information We Collect

1. Personal Information You Provide

Account Information

When you create an account, we collect:

• Email address (via Google Sign-In or Apple Sign-In)
• Name (via Google Sign-In or Apple Sign-In)
• Profile photo URL, if provided
• Unique user identifiers (Firebase UID, RevenueCat customer ID)

Authentication Data

• Firebase Authentication tokens for secure session management
• OAuth tokens from Google or Apple for authentication purposes

2. Usage Information

Text Processing Data

When you use Twik's grammar correction and writing assistance features:

• Text you explicitly submit for AI processing (grammar correction, rewriting, tone adjustment)
• Selected writing mode or tone (e.g., General, Professional, Sarcastic, Gen Z)
• API request metadata (timestamps, request counts)

Important: we only process text that you explicitly submit for AI suggestions — on Android, this means typing "#" and tapping the correction button; on iOS, this means text submitted through the keyboard extension with Full Access enabled. We do not collect or store any other text you type. Text is sent to our secure Supabase backend for processing and is not permanently stored beyond caching for performance optimization.

Subscription Information

• Subscription status (free, active, canceled, expired)
• Product IDs of purchased subscriptions
• Purchase dates and expiration dates

Usage Tracking

• Unique device identifiers (for authentication and analytics)

Technical Data

• Text typed on your device unless explicitly submitted for AI processing

Your Rights and Choices

Access and Update Information

You can view and update your account information within the App settings.

Delete Your Account

You have the right to delete your account at any time by opening the Twik app, navigating to Settings, and tapping "Delete Account" — or by contacting us at twikappai@gmail.com.

What gets deleted

• All user data from our Supabase database (user profile, usage statistics)

Accessibility Service / Keyboard Access

On Android, you can revoke Accessibility Service permission at any time in Settings → Accessibility. On iOS, you can enable or disable "Full Access" for the Twik keyboard in Settings → General → Keyboard → Keyboards → Twik. Without these permissions, the App cannot connect to our servers for AI processing.

Subscription Management

You can manage or cancel your subscription through Google Play (Settings → Google → Subscriptions) or the App Store (Settings → your name → Subscriptions), depending on your device.

Data Security

We implement industry-standard security measures to protect your information:

• Encryption in Transit: all data transmitted between the App and our servers uses HTTPS/TLS encryption
• Secure Authentication: Firebase Authentication with OAuth 2.0 for Google and Apple Sign-In
• Token Security: authentication tokens are securely stored on-device (Android Keystore / iOS Keychain)
• Access Controls: database access is restricted using row-level security policies
• No Plaintext Storage: sensitive data is never stored in plaintext

However, no method of transmission over the internet or electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your information, we cannot guarantee absolute security.

Children's Privacy

The App is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us at twikappai@gmail.com, and we will delete such information.

International Data Transfers

Your information may be transferred to and maintained on servers located outside of your state, province, country, or other governmental jurisdiction where data protection laws may differ, including the United States and other regions where our service providers operate. By using the App, you consent to the transfer of your information to our servers and our third-party service providers.

For users in the European Economic Area (EEA)

• We rely on standard contractual clauses approved by the European Commission for data transfers
• Our third-party providers (Firebase, Supabase, RevenueCat) are compliant with GDPR
