Third-Party Services and Advertising Disclosure

Last updated: 2026-09-10

This page lists every third-party service 4Dev.net's tools actually connect to, so nothing about outbound requests your browser makes while using the site is a surprise.

1. Data Providers

  • Frankfurter (api.frankfurter.dev) - live exchange rates for major currencies.
  • fawazahmed0/currency-api, served via jsDelivr and a Cloudflare Pages fallback - broader currency and cryptocurrency rate data.
  • flagcdn.com - flag icon images.
  • CoinCap (assets.coincap.io) - cryptocurrency icon images.

2. Code Libraries (CDN-Hosted)

  • cdnjs.cloudflare.com - FileSaver.js (file downloads) and Mammoth.js (Word document reading).
  • cdn.jsdelivr.net - fast-xml-parser and sql-formatter.
  • cdn.sheetjs.com - the SheetJS/xlsx library, for spreadsheet reading and writing.
  • fonts.googleapis.com / fonts.gstatic.com - the Inter typeface (Google Fonts).

3. Analytics

The Website's infrastructure is configured to be able to support Google Analytics in the future, but as of the date above, no analytics script is loaded and no analytics tracking is active. If this changes, this page and the Cookie Policy will be updated in advance.

4. Advertising

4Dev.net does not currently display advertising. If advertising is introduced in the future, this page will be updated to disclose the ad network(s) used and their data practices before ads go live.

5. Your Relationship With Third Parties

4Dev.net's own code does not store your data or keep logs of it - but the services listed above are operated by their own providers, under their own data practices, which we don't control. 4Dev.net is not responsible for, and makes no guarantee about, the content, availability, security, or privacy practices of any third-party service, API, or embedded off-the-shelf library listed on this page - our commitment to not storing or logging data covers what we build, not what these external providers do on their end. Your use of those services (even indirectly, through this Website) is subject to their own terms and privacy policies.
