Privacy Policy

Last updated: May 9, 2026

This Privacy Policy explains how Proxylang, operated by TITUS TIMOTHY DAVID ("Company," "we," "us," or "our"), collects, uses, and protects information when you use our website translation proxy service ("Service").

By using our Service, you agree to the collection and use of information as described in this policy. We are committed to protecting your privacy and being transparent about our data practices.

1. Information We Collect

1.1 Account Information

When you create an account, we collect:

  • Email address
  • Name (optional)
  • Password (encrypted)
  • Company name (optional)
  • OAuth provider information (if using social login)

1.2 Domain and Configuration Data

When you configure the Service, we store:

  • Domain names you register for translation
  • Source and target language preferences
  • Widget customization settings
  • Translation exclusion rules

1.3 Website Content (Processed Temporarily)

When translating your website, we process:

  • Text content from your web pages
  • HTML structure (for translation targeting)
  • URL paths and page structure
  • Meta tags and SEO content

Note: We do not permanently store your original website content. Content is processed in real-time and only cached translations are retained.

1.4 Usage and Analytics Data

  • Translation request counts and patterns
  • Page views per language
  • Geographic distribution of requests (country, region, and city level)
  • Response times and performance metrics
  • Error logs and debugging information

For Full Proxy mode customers, we additionally store a pseudonymous visitor identifier (derived from a salted hash of IP and User-Agent — the raw IP is never retained), session identifier, browser, operating system, and device type, on the customer's behalf as a data processor. WordPress plugin Hybrid mode does not collect visitor analytics.

1.5 Payment Information

Payment processing is handled by Polar (international card payments via Stripe). We do not store credit card numbers or full payment details. We only store:

  • Subscription status and tier
  • Customer ID (from payment provider)
  • Billing history and invoice records

1.6 Information We Do NOT Collect

  • User passwords from your website's visitors
  • Private messages or user-generated content (unless publicly displayed)
  • Payment information from your website's customers
  • Content from password-protected pages (unless explicitly proxied)
  • Personal information about visitors to your translated website

2. How We Use Information

We use collected information to:

  • Provide the Service: Translate and serve your website content
  • Improve Performance: Cache translations, optimize delivery, reduce latency
  • Analytics: Show you usage statistics and language distribution
  • Billing: Process payments and manage subscriptions
  • Support: Respond to your inquiries and troubleshoot issues
  • Security: Detect and prevent abuse, fraud, and security threats
  • Communication: Send service updates, usage alerts, and important notices
  • Legal Compliance: Meet regulatory and legal obligations

3. AI Translation and Third-Party Data Sharing

Important: Your content is processed by third-party AI services for translation. Please review this section carefully.

3.1 Translation Providers

Text content from your website is sent to third-party translation providers for processing. Depending on the target language or use case, translation providers may include DeepL, Google, Anthropic, OpenAI, or other AI providers operated by Proxylang.

All personally identifiable information is automatically redacted prior to transmission to any translation provider. No submitted text is used to train AI models.

3.2 PII Protection Before Translation

Before sending content to translation providers, we automatically detect and redact personal information, including:

  • Email addresses
  • Phone numbers
  • Physical addresses
  • Credit card numbers
  • Social security numbers
  • Other identifiable patterns

Redacted content is replaced with placeholder tokens during translation and restored in the final output.

3.3 What We Send to Providers

  • Sent: Text content with PII removed, source/target language codes
  • NOT Sent: Your user data, authentication credentials, images, media files, your visitors' personal information

3.4 AI Provider Data Usage

We use API-only access to translation providers:

  • Content is processed solely for the purpose of translation
  • Providers may retain content temporarily for abuse prevention
  • Content is not used to train any AI models

You can clear cached translations for your domain at any time through the dashboard. This will remove all translated content from our caches.

6. Cookies and Tracking

6.1 Cookies We Use

  • Authentication: Session cookies to keep you logged in
  • Language Preference: Cookie to remember visitor language selection (proxylang_lang)
  • Theme Preference: Cookie to remember dark/light mode

6.2 Cookies We Do NOT Use

  • Third-party advertising cookies
  • Cross-site tracking cookies

6.3 Visitor Tracking on Translated Sites

Visitor tracking depends on the integration mode:

  • WordPress plugin (Hybrid mode): We do not collect any per-visitor analytics. Only the requested URL path and the visitor's User-Agent are transmitted, and only for search-engine bot requests.
  • Full Proxy mode: On the customer's behalf as a data processor, we collect a pseudonymous visitor identifier (salted hash, raw IP discarded), session identifier, country/region/city, browser, operating system, and device type. We do not link this data to a real-world identity. The customer is the data controller and is responsible for disclosing this collection in their own privacy notice and obtaining any required visitor consent.

7. International Data Transfers

Your data may be processed in multiple jurisdictions:

  • Edge Processing: Global CDN network (300+ locations worldwide)
  • AI Translation: Third-party translation providers (various jurisdictions)
  • Database & Cache: Distributed infrastructure (multiple regions)

7.1 Safeguards

For international data transfers, we rely on:

  • Standard Contractual Clauses (SCCs) with providers
  • Provider certifications (SOC 2, ISO 27001 where applicable)
  • Data Processing Agreements (DPAs)

7.2 EU Users (GDPR)

For GDPR purposes, we act as a "data processor" when translating your website content. You (the website owner) remain the "data controller" and are responsible for:

  • Ensuring you have appropriate legal bases for processing visitor data
  • Providing privacy notices to your website visitors
  • Responding to data subject requests from your visitors
