Privacy Policy

Effective date: April 2026  ·  Version 1.0

Our commitment in one sentence Your personal property data belongs to you and stays on your device. We do not have user accounts, we do not maintain a user database, and we do not know who you are.

1. What We Collect and Where It Lives

1.1 Data stored only on your device

The following data is stored exclusively in your device's local storage (encrypted Hive database) and is never transmitted to any server:

DataWhere storedWho can access

We have no access to any of this data. We cannot retrieve it, view it, or share it.

1.2 Google Drive Backup (optional)

When you choose to back up your data to Google Drive, 2scale encrypts all data using AES-256 encryption on your device before uploading. The encrypted file is stored in your personal Google Drive app folder — only accessible to you. 2scale cannot read, access, or share your backup. Your Google account credentials are never stored by 2scale.

1.3 Data that leaves your device

The following data leaves your device only in specific circumstances you initiate:

2. Data We Do Not Collect

2scale does not collect, store, or transmit:

3. Google Services We Use

Google Drive API

Used solely when you initiate a backup. 2scale requests access to the drive.appdata scope — a private, app-specific folder in your Google Drive that only 2scale can access. We upload your AES-256 encrypted backup file. We cannot access any other files in your Drive.

Google Gemini API

Used when you use 2scale AI or AI document analysis. Only your question text or extracted document text is sent. No personal data, property details, or original files are transmitted.

Firebase Firestore and Storage

Used for anonymous community area submissions and distributing aggregated community data. No personal data is stored.

Google AdMob

Used in the free version to serve advertisements. To avoid AdMob: upgrade to 2scale AI subscription (removes all ads).

4. Data Security

All sensitive data — properties, documents, and reminders — is encrypted at rest using AES-256 via the Hive encrypted database. The encryption key is stored in your device's secure hardware keystore (Android Keystore / iOS Secure Enclave), never in plain text.

When you back up to Google Drive, data is encrypted on your device before upload. The decryption key never leaves your device.

5. Data Retention and Deletion

All personal data is stored only on your device. It is deleted when you:

We cannot recover deleted data. Back up important documents independently.

Community submissions are stored on Firebase and retained indefinitely as part of the aggregated knowledge base. Individual submissions cannot be deleted once aggregated.

6. Your Rights

Under India's Digital Personal Data Protection Act 2023, you have the right to:

7. Children's Privacy

2scale is not intended for users under 18. We do not knowingly collect data from minors.

8. Changes to This Policy

When this policy is updated, the version number and effective date will change and you will be notified in the app. We will not make changes that reduce your privacy protections without clear notification.

We aim to respond to all privacy enquiries within 7 business days.

Plain language summary We don't know who you are. Your property data never leaves your phone. The only things that leave your device are: AI questions you explicitly send, anonymous community ratings you voluntarily submit, and area names when fetching ads. We don't sell your data. Ever.
