Privacy Best Practices

Protecting user privacy builds trust and reduces legal risk. For browser-based tools that process user files, follow these best practices: minimize data collection, be transparent about third-party services, and provide clear consent for tracking and advertising.

Process files locally when possible

Client-side processing keeps user files in the browser and avoids server uploads. This reduces exposure and limits the need for data retention policies. When server processing is required, delete files promptly and inform users how long temporary copies will be stored.

Be transparent in the privacy policy

Explain what data is collected, why it is collected, and how it is used. Describe advertising partners, measurement tools, and any automated decision-making. Provide straightforward instructions for opting out of tracking and targeted advertising.

Consent and cookie management

Offer granular consent choices and respect opt-out preferences. Do not load advertising or tracking scripts until the user has given explicit consent for that behavior. Store consent records and honor them across sessions where possible.

Secure handling of user data

If your site accepts uploads, use TLS for uploads and downloads, validate file types, and scan for harmful content if necessary. For any retained data, follow least-privilege principles and limit access to a small set of service accounts.

By adopting privacy-first approaches, you will improve user trust, reduce friction, and make your site more attractive to privacy-aware visitors and partners.
