4. How We Use Collected Information

We use the collected information for the following purposes:

• Analyzing Service usage for improvement
• Displaying relevant ads through Google AdSense
• Detecting and preventing abuse through rate limiting (max 60 requests per minute per IP)

5. Abuse Protection (Rate Limiting)

To protect the Service from abuse, we use rate limiting via Cloudflare KV. Your IP address is temporarily stored in the Cloudflare KV database along with request timestamps. This data is automatically deleted after double the time window (120 seconds). Rate limiting restricts API requests to 60 per minute per IP address.

6. Data Security

Your data security is our priority. We implement appropriate technical and organizational measures to protect collected information from unauthorized access, loss, or destruction.

Our security measures include:

• SSL/TLS connection encryption
• Hosting on secure Cloudflare Workers infrastructure
• Regular security audits
• Data collection minimization
• Automatic deletion of rate limiting data after specified time (TTL)

7. Sharing Data with Third Parties

We do not sell, rent, or share your personal data with third parties, except:

• Google AdSense: for displaying ads (in accordance with their privacy policy)
• Cloudflare: hosting infrastructure provider (Workers, D1, KV) and DDoS attack protection
• Legal requirements: when required by law or in response to legitimate law enforcement requests
