Privacy Policy
Last updated: October 7, 2026
1. Overview and Core Philosophy
MrFreqline ("we", "our", or "us"), operating at https://mrfreqline.com, respects the privacy of our visitors. Our fundamental architecture is built around minimal data collection. We do not require account creation, logins, or paid subscriptions to access our curated resource directories or browser utilities.
2. Client-Side Tools and Zero-Data Architecture
A core pillar of MrFreqline is our suite of in-browser utilities, including PDF tools (merging, splitting, compressing), GPA and CGPA calculators, image converters, hashing tools, Preeti-to-Unicode converters, and system calculation utilities.
- No Server Uploads: Files, documents, images, and text inputs submitted inside these tools are processed 100% locally within your device's browser using client-side JavaScript and WebAssembly.
- No Server Retention: Your files never travel across the internet to our backend servers. Once you close or reload the browser tab, in-memory processing data is immediately discarded.
3. Information We Collect
We only receive information under the following limited conditions:
A. Community Reviews and Suggestions: When you submit a review on our reviews page, you may optionally provide a display name, rating, and written comment. Providing a phone number is optional; if provided, phone numbers are kept private and are never displayed publicly.
B. Anonymous Feedback: Messages submitted via our contact portal are transmitted securely to allow our administrative team to review site suggestions and error reports.
C. Standard Technical Logs: Like most web servers, our hosting infrastructure may collect non-personally identifiable log information such as browser type, operating system, referring URL, and timestamp to monitor system health and mitigate DDoS threats.
4. Local Browser Storage
We use browser localStorage strictly to preserve your user preferences between visits, including:
- Selected interface theme and light/dark mode preference
- Bookmarked and favorite tool selections
- Dismissal status of educational and informational banners
This data resides entirely on your device and can be cleared at any time via your browser settings.
5. Third-Party Advertising and External Links
To keep our infrastructure and utility tools freely accessible without charging fees, MrFreqline displays non-intrusive banner advertisements through third-party advertising partners (such as Adsterra).
These third-party ad networks may use standard web cookies or browser identifiers to serve context-relevant ads. You can manage or disable advertising cookies at any time through your browser privacy settings or third-party opt-out mechanisms.
Our directory features curated links to external websites, open-source repositories, and digital resources. We are not responsible for the privacy practices, content, or terms of third-party websites. We encourage you to review their policies upon visiting.
6. Your Privacy Rights and Data Requests
Depending on your location, you may have rights under data privacy frameworks such as GDPR or CCPA, including the right to request access to or deletion of feedback you previously submitted to our platform.
To request deletion of any review or message you previously submitted, reach out to us directly through our Contact Page.
7. Policy Updates
We may periodically update this policy to reflect platform updates, technical adjustments, or regulatory requirements. Any modifications will be posted directly to this page with an updated timestamp.
