Privacy Policy
Last Updated: July 4, 2026
Welcome to Tool Yaar : Smart Utilities ("Tool Yaar", "App", "we", "our", or "us"), developed and operated by Dipanshu Kumar.
Your privacy is important to us. This Privacy Policy explains what information the App collects, how it is used, how it is protected, and the choices available to you when using the App.
Tool Yaar is designed with a privacy-first approach. Most of the App's features work entirely on your device without requiring you to create an account or upload your personal data to our servers.
By downloading, installing, or using Tool Yaar, you agree to the practices described in this Privacy Policy.
1. Information We Collect
1.1 No Mandatory Account
Tool Yaar does not require users to create an account or sign in before using the App.
Most features are immediately available without registration.
1.2 Optional Profile
During the initial setup, users may optionally choose to:
Enter a display name
Select or capture a profile picture
This setup is completely optional and can be skipped.
The profile information is stored only on your device and is never uploaded to our servers.
1.3 User Generated Content
Depending on the utilities you use, the App may create or store information such as:
Notes
To-Do Lists
Expense records
Water Reminder schedules
Event Countdown data
Calculator history
QR scan history
Speed Test history
Secure Space files
User preferences
This information remains stored locally on your device unless you explicitly export or share it yourself.
We do not upload this information to our servers.
2. Local Data Storage
Tool Yaar is designed so that most user data remains entirely on the user's device.
Examples include:
Profile information
History
Notes
Reminder schedules
Expenses
Secure Space files
Calculator results
User settings
The App uses Android's local storage mechanisms, including Room Database and private application storage where appropriate.
Removing the App or clearing its storage may permanently delete locally stored information.
3. Secure Space
Tool Yaar includes a feature called Secure Space, which allows users to securely protect selected files on their device.
Secure Space uses modern cryptographic standards including:
AES-256-GCM encryption
PBKDF2 with HMAC-SHA256
65,536 key derivation iterations
Encryption keys are generated locally on the user's device.
Encrypted files remain stored exclusively on the device and are never uploaded to our servers.
Secure Space is protected using a password chosen by the user.
Because the password is known only to the user, we cannot recover forgotten passwords or decrypt protected files.
4. On-Device Processing
One of Tool Yaar's core privacy principles is that as much processing as possible happens locally.
Many utilities perform their work directly on your device without uploading your files or personal content.
Examples include:
