Privacy Policy

1. Data Controller

The data controller responsible for data processing on this website is:

pricewatcha.com - Kamilla Straß
c/o Online-Impressum.de #5893
Europaring 90
53757 Sankt Augustin
Email: info@pricewatcha.com

2. General Information

We take the protection of your personal data seriously. We process your personal data confidentially and in accordance with applicable data protection laws, in particular the General Data Protection Regulation (GDPR) and this privacy policy.

Personal data is any information that can be used to identify you personally, such as your email address.

3. Hosting

This website is hosted by Railway. The application is operated on servers located within the European Union, currently in the Netherlands.

During hosting, personal data necessary for the operation and provision of the website (e.g. IP addresses and technical log data) is processed.

The processing is based on Art. 6(1)(f) GDPR (legitimate interest in a secure and efficient operation of the website).

4. Registration and Use of the App

Registration is required to use Pricewatcha.

As part of registration and usage, we process in particular the following personal data:

This data is processed solely for the purpose of providing the Pricewatcha service.

The processing is based on Art. 6(1)(b) GDPR (performance of a contract).

5. Database and Authentication

We use Supabase for authentication and data storage.

Supabase processes email addresses and application-related data required to operate Pricewatcha.

The processing is based on Art. 6(1)(b) GDPR.

6. Email Delivery

We use Resend to send system-related emails (such as verification emails, price alerts and service notifications).

Your email address is processed solely for the purpose of sending these emails.

The processing is based on Art. 6(1)(b) GDPR.

7. Browser Extension (optional)

For many platforms, an optional browser extension can be used as an alternative to server-side scraping, especially when regular product capture fails.

When using the extension, product-related data (e.g. URL, title, price and currency) is extracted from the currently opened product page and sent to our Pricewatcha server so the product can be added or updated in Pricewatcha.

The extension stores only technically required local browser data (e.g. authentication status, API base URL and already processed URLs) to provide its functionality.

Processing is based on Art. 6(1)(b) GDPR (performance of a contract) and Art. 6(1)(f) GDPR (legitimate interest in stable and user-friendly product capture).

8. API and AI Assistant Access (MCP)

Pricewatcha can also be used via our public API and via AI assistants such as Claude or ChatGPT, through our remote MCP server at https://mcp.pricewatcha.com. These access methods can be used without a user account.

When you submit a product URL or search query this way, we process the submitted URL or query and technical data (e.g. IP address for rate limiting) to return the requested price information; no email or account data is required or collected for anonymous use. The data handling, hosting and third-party processing described elsewhere in this policy applies equally.

9. Price retrieval / scraping providers

To retrieve product prices, submitted product URLs may be processed by third-party scraping service providers acting on our behalf, in addition to our own crawler. These providers receive the product URL to fetch the publicly available product page.

10. Third-Country Transfers

It cannot be ruled out that personal data processed by our service providers may also be transferred to third countries.

In such cases, data transfers are carried out based on appropriate safeguards in accordance with Art. 46 GDPR, including contractual safeguards or recognized data protection standards.

11. Web Analytics

We use two web analytics services to evaluate how our website is used anonymously and to improve the stability and usability of Pricewatcha.

Umami (self-hosted)

Pricewatcha uses the self-hosted web analytics service Umami (client- and server-side). No cookies are set, no advertising or marketing profiles are created, and no direct identification data (e.g. name or email) is linked to user accounts.

Aggregated or pseudonymous usage data is processed, such as visited pages and URL paths, referrers, browser and device information, and technical events such as product interactions (platform, product ID, product URL), API calls (endpoint, method, status, client IP), or search queries via the public API — solely to improve stability and usability, not for advertising purposes.

For client-side website visits, the IP address is not stored permanently; Umami uses it only to derive an approximate location (country/city). For server-side API events we store the client IP as event metadata so we can investigate abuse and stability issues.

Processing is based on Art. 6(1)(f) GDPR (legitimate interest in usage analysis and in detecting abuse of the public API).

Ahrefs Web Analytics

We also use Ahrefs Web Analytics, a web analytics service provided by Ahrefs Pte. Ltd. (Singapore). The tracking script is loaded from analytics.ahrefs.com.

Ahrefs collects aggregated usage data, including visited page URLs, referrers, browser and device information (user agent), approximate location (country and city, derived from the IP address) and language settings. Ahrefs does not permanently store IP addresses after processing. No cookies are set, no cross-device or cross-website profiles are created and no data is used for advertising purposes.

Processing may take place outside the EU/EEA; the safeguards described in section 10 apply. The legal basis is Art. 6(1)(f) GDPR (legitimate interest in anonymous usage analysis). For more information, see the Ahrefs privacy policy.

12. Data Retention

Personal data is stored only for as long as necessary to fulfill the respective purposes or as required by statutory retention obligations.

Once the purpose no longer applies or a user account is deleted, the corresponding data will be deleted unless legal retention requirements apply.

13. Your Rights and Account Deletion

You have the right at any time to:

You can also delete your user account at any time directly within the application: Delete account

When a user account is deleted, authentication data and all personal data associated with the user account are removed. Product and price data may remain stored but are no longer associated with any identifiable user.

You also have the right to lodge a complaint with a competent data protection supervisory authority.

14. Changes to This Privacy Policy

We reserve the right to update this privacy policy to reflect changes in legal requirements or updates to Pricewatcha. The current version is always available on this website.
