Privacy Policy

Last updated: October 2026

Aligner Time respects your privacy. This Privacy Policy explains how your information is collected, used, and protected when using the app.

Information We Collect

• Mobile phone number used to create, identify, and verify your account.
• Account information used to create and manage your account.
• Aligner wear sessions, including start and stop times.
• Daily wear-time totals and history.
• Your personal wear-time goals and app preferences.
• Technical information required to operate and secure the app.

Phone Number & WhatsApp Verification

Aligner Time uses your mobile phone number for account registration, identification, authentication, and to associate your account with your saved Aligner Time data.

To verify your phone number, Aligner Time may send a One-Time Password (OTP) through WhatsApp. The OTP is used only to confirm that you have access to the phone number provided during registration or login.

Your phone number may be stored securely as part of your Aligner Time account and used to maintain access to your saved wear-time history, preferences, and other account-related data.

WhatsApp is a third-party service. Delivery of verification messages through WhatsApp may be subject to WhatsApp's own terms, privacy practices, availability, and technical requirements.

Data Sharing

We do not sell your personal information. Information may be processed by trusted service providers required to operate the app, including authentication, database, hosting, and notification services.

Data Security

We use reasonable technical and organizational measures to protect your information. However, no electronic storage or transmission system can guarantee absolute security.

Account & Data Deletion

You may request deletion of your account and associated personal information. Certain information may be retained where required by law or for legitimate security purposes.

Notifications

Aligner Time may send wear-time reminders and other app-related notifications. You can manage notification permissions through your device settings.
