Privacy policy.
Last updated: September 1, 2026 • Clear, transparent, and built on a zero-data-collection architecture.
Your data stays on your machine. Always.
Every calculation is executed entirely inside your web browser via client-side JavaScript. We do not operate user accounts, we do not log your activity, and we never sell data.
1. Executive Overview & Website Scope
Free Data Usage ("we", "our", or "us"), accessible from datausagetoday.com, operates an independent web utility designed to assist users in calculating mobile and broadband data consumption. This Privacy Policy details our handling of user information and our structural commitment to data minimization.
2. Information We Do NOT Collect
Our technology stack is engineered to run client-side. We do not collect, capture, transmit, or monetize any of the following:
- Personal Identifiers: Names, email addresses, phone numbers, or mailing addresses.
- Calculation Inputs & Outputs: Selected device counts, daily streaming hours, gaming minutes, or computed gigabyte totals.
- Billing & Carrier Information: Your cellular network operator, contract pricing, or account numbers.
- Tracking Identifiers: Advertising IDs (IDFA, GAID), fingerprinting telemetry, or third-party cookies.
- IP Addresses: Server logs do not associate requests with personal identities.
3. Client-Side Execution & Browser Local Storage
When you interact with the sliders and toggles on our website, JavaScript processes the mathematical equations locally on your computing device (CPU). We utilize your browser's localStorage strictly for two optional user-convenience functions:
Stores your light or dark mode visual interface preference so that pages render smoothly without flashing on return visits.
Preserves your active calculator slider values locally so your inputs are not lost if you accidentally refresh the page. This data remains on your device and is never transmitted.
4. URL Hash Sharing Parameters
When you generate a shareable calculation link, your inputs are serialized into a URL hash fragment (e.g., #calc=...). According to RFC 3986 standards, URL hash fragments are handled exclusively by your client web browser and are never transmitted across the network in HTTP GET requests to our hosting infrastructure.
5. Third-Party Services & External Links
Free Data Usage is hosted on high-performance static content delivery networks (CDNs). We do not include third-party marketing SDKs, social media tracking widgets, or ad-network scripts. Our educational guides may contain outbound links to official technical documentation (such as Netflix or Cisco). Visiting external websites is subject to the respective third party's privacy policies.
6. Global Privacy Compliance (GDPR, CCPA & PECR)
Because our service operates on a strict zero-data-collection principle:
- We do not process "personal data" as defined by the European Union General Data Protection Regulation (GDPR).
- We do not "sell" or "share" consumer personal information under the California Consumer Privacy Act (CCPA/CPRA).
- We do not deploy non-essential tracking cookies requiring PECR / ePrivacy consent banners.
7. Policy Modifications & Contact
We reserve the right to revise this Privacy Policy to reflect technical updates or legal standards. Revisions will be posted here with an updated "Last updated" timestamp. If you have questions regarding this policy, please reach out via our contact page or email hello@datausagetoday.com.
