Cookie Policy
This page explains the cookies and similar technologies used by PDF99, why we use them, and how you can control them.
What are cookies?
Cookies are small text files stored on your device by websites you visit. They help websites remember your preferences and improve functionality. We also use similar technologies (local storage, pixels) for analytics and performance.
Why we use cookies
We use cookies to:
- Remember user preferences (e.g., language, UI choices).
- Provide site functionality and keep sessions secure.
- Collect anonymized analytics to improve performance and fix errors.
- Support optional features such as remembering consent choices.
Cookie categories
Category | Purpose | Examples & retention |
---|---|---|
Essential | Required for the site to function (session, security). | Session identifiers - expire when the session ends or within 24 hours. |
Preferences | Remember user settings (language, UI preferences). | Language/UI cookies - typically 1 month to 1 year. |
Analytics | Anonymous usage metrics to improve performance and reliability. | Google Analytics / similar - 14 months (or provider default). |
Marketing (third-party) | Used by third parties for advertising and tracking across sites (if enabled). | Depends on third-party provider; often 30 days to 2 years. |
Third-party cookies
We use third-party services (e.g., analytics, CDN, error monitoring). Those providers may set their own cookies; we do not control their retention policies. Examples of third parties we may use include Google Analytics, Cloudflare, and Sentry. Consult each provider’s privacy page for details.
How to manage cookies
You can control cookie preferences in several ways:
- Use the cookie controls provided by this site (if visible) to enable/disable non-essential cookies.
- Disable or clear cookies in your browser settings - see your browser’s help for instructions.
- Use browser extensions that block trackers or use your browser’s Do Not Track setting (note: blocking some cookies may break features).
Opt-out links (examples)
Some analytics and advertising providers offer opt-out options. Examples (visit the provider for the latest tools):
- Google Analytics opt-out browser add-on
- Network Advertising Initiative - consumer opt-out tools
(Note: the links above are illustrative. For up-to-date opt-out tools, visit the respective provider websites.)
Do we use cookies for files?
We do not store file contents in cookies. Files uploaded for processing are treated as User Content and are handled according to our Privacy & Security policy.
Data retention
Cookie retention times depend on cookie type and provider. Essential cookies are short-lived; analytics and marketing cookies are set per provider defaults. You can remove cookies at any time using browser controls.
Changes to this Cookie Policy
We may update this policy from time to time. Significant changes will be posted here with an updated effective date.
