Privacy Policy

Effective Date: August 19, 2025

This Privacy Policy describes how Lines ("we," "us," or "our") collects, uses, and protects your information when you create an account and use our iOS application (the "App") and our website (the "Site").

Your privacy is important to us. By creating an account and using our App or Site, you agree to the collection and use of information in accordance with this policy. If you do not agree with this policy, please do not create an account or use our services.

1. Information We Collect

We collect information in two ways: information you provide directly when creating an account, and information collected automatically through analytics once you are logged in.

A. Information You Provide to Us:

Account Information: To use Lines, you must create an account. When you do so, we collect your email address and a hashed password. We need this information to create and secure your account and allow you to log in across devices.

B. Information We Collect Automatically (Analytics Data):

Once you have created an account and are using our services, we automatically collect certain information to help us improve the App and Site. This analytics data is directly associated with your account.

We use PostHog Cloud for our analytics. We have specifically configured our PostHog service to ensure that all data is hosted and processed on servers located within the European Union (EU). This means your data is protected by the high privacy standards of the General Data Protection Regulation (GDPR).

The analytics data associated with your account includes:

  • Usage Data: Information about how you interact with our services, such as the features you use, screens you visit, buttons you tap, and session duration. This helps us understand which features are most valuable and where we can make improvements.
  • Device Information: Information about the device you are using, such as the device model (e.g., 'iPhone 15'), and operating system version (e.g., 'iOS 18.1').
  • User Account Identifier: Your account is assigned an identifier that allows us to connect your usage data across sessions and devices.

We do not collect or analyze the specific lyrics you input or memorize. This content is considered your private data and is not used for our analytics.

2. How We Use Your Information

Our legal basis for collecting and using the information described above is your consent, which you provide by creating an account and agreeing to this Privacy Policy. We use your information for the following purposes:

  • To Provide and Maintain Your Account: To create your user account, authenticate you, and save your progress.
  • To Analyze and Improve Our Services: To understand user behavior, fix bugs, enhance the user experience, and make informed decisions about new features.
  • To Communicate With You: We may use your email address to send you important information about your account or our services (e.g., password reset emails, major policy updates).

3. Data Processing and Third-Party Services

We use PostHog's Cloud service to process and analyze the usage data we collect. As mentioned, we use their EU-based cloud infrastructure, which ensures your data does not leave the European Union and is handled in compliance with GDPR. PostHog acts as a data processor on our behalf and is contractually obligated to protect your data.

You can learn more about PostHog's privacy and security practices on their website.

4. Data Sharing and Disclosure

We do not sell, trade, or rent your personal information to third parties. We may only disclose your information in the following limited circumstances:

  • Service Providers: We share information with third-party service providers like PostHog who perform services on our behalf, under the strict obligation to keep your information confidential and secure.
  • Legal Obligation: If required to do so by law or in response to valid requests by public authorities (e.g., a court or a government agency).
  • Business Transfer: If we are involved in a merger, acquisition, or asset sale, your information may be transferred as a business asset.

5. Data Retention

We retain your personal information for as long as your account is active. If you choose to delete your account, we will take steps to permanently delete your personal information and associated analytics data from our systems within a reasonable timeframe, in accordance with our data deletion policies.

6. Your Data Rights under GDPR

As your data is personally identifiable and linked to your account, you have strong rights over it under the GDPR.

  • Right of Access: You have the right to request a copy of the personal data we hold about you.
  • Right to Rectification: You have the right to request that we correct any information you believe is inaccurate.
  • Right to Erasure (Right to be Forgotten): You have the right to request the deletion of your account and all associated personal data.
  • Right to Object to Processing: You have the right to object to our processing of your personal data.

To exercise any of these rights, please contact us at the email address provided below. The easiest way to have your data erased is to request the deletion of your account.

7. Data Security

We are committed to protecting your information. We implement appropriate technical and organizational measures to safeguard your data. You are also responsible for keeping your account password confidential.

8. Children's Privacy

Our services are not intended for use by children under the age of 13 (or 16 in certain EEA jurisdictions). We do not knowingly collect personally identifiable information from children. If you are a parent or guardian and you believe your child has provided us with information without your consent, please contact us.

9. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any material changes by posting the new Privacy Policy on this page and/or by sending an email to the address associated with your account.
