Privacy at a glance

- You control how your data is used
Tooltails provides free online utility tools for age calculation, date math, and productivity tracking. We built this service with a simple principle: your data belongs to you.
This policy describes what information we access, how it is used, and the controls available to you. It applies to all pages and tools on tooltails.com, including Tooltails Focus and Tooltails Pomodoro Timer.
Information We Collect
We intentionally limit data collection. Here is what we access:
Automatically collected (analytics)
- - Page URL and referring domain
- - Browser type and device category
- - Approximate geographic region (country-level)
- - Session duration and interaction events
Not collected
- - Names, email addresses, or phone numbers
- - Dates of birth or personal identifiers
- - Passwords or account credentials
- - Payment or financial information
How We Use Information
The limited data we access serves two purposes:
- 1 Improve the product. Analytics help us understand which tools people use and how the site performs, so we can fix bugs and prioritize features.
- 2 Keep the service free. Non-personalized and personalized ads help cover infrastructure costs. You can opt out of personalization at any time.
Advertisements
We use Google AdSense to display advertisements on select pages. AdSense may use cookies and web beacons to serve ads based on your prior visits to this site and other sites across the internet.
You can opt out of personalized advertising by visiting Google's Ads Settings at myadcenter.google.com or the Digital Advertising Alliance at youradchoices.com.
Data Storage
Where and how your data lives depends on the tool you are using:
| Tool | Storage location | Data transmitted |
|---|---|---|
| Age Calculator | In-memory (discarded on navigation) | None |
| Focus Timer | Browser localStorage | None |
| Pomodoro Timer | Browser localStorage | None |
| Word Counter | In-memory (discarded on navigation) | None |
Third-Party Services
Our site integrates with the following third-party services:
- G Google Analytics (GA4) - Aggregated traffic analysis and event tracking.
- C Microsoft Clarity - Session replay and heatmap analysis for UX improvement.
- A Google AdSense - Advertisement delivery and personalization.
Each service operates under its own privacy policy. We encourage you to review their policies for complete transparency.
Security
We serve the entire site over HTTPS to encrypt data in transit. Since we do not collect or store personal data on our servers, the primary security consideration is your local browser environment. We recommend keeping your browser and operating system updated to protect against local vulnerabilities.

- - Right to know. This policy describes what data is accessed and why.
- - Right to opt out. You can disable analytics cookies and personalized ads via browser settings.
- - Right to delete. Clear your browser's localStorage and cookies to remove any locally stored data.
- - Right to access. Contact us with questions about data practices.

We do not sell, trade, or transfer your personal information. Third-party services like Google Analytics and AdSense have their own privacy policies governing data they collect.
