Third-party notices & data sources

Updated September 11, 2026

Built with open-source software

Atlas Budgeting is operated by PKM Software, based in Texas, United States. The app and website include software and fonts created by other developers. Those components retain their own copyrights and licenses. Their inclusion does not imply that their authors endorse Atlas.

Read the complete notice collections below. Components vary by platform and build; the app collection covers the reviewed Atlas 1.4 codebase and includes native-library and font notices. Website notices also include build and server dependencies; those are not all delivered to your browser.

These licenses apply to their respective components. They do not change the license of unrelated Atlas code or the rights granted by another component’s license.

Exchange-rate data

Atlas calculates currency estimates using dated European Central Bank reference rates retrieved through Frankfurter. The underlying reference data is available free of charge from the European Central Bank.

Atlas derives cross-currency estimates and reporting totals from this data. These calculations are Atlas’s, not official ECB transaction quotes. Reference dates appear in the app. Bank settlement rates, fees and actual charges can differ; unsupported or unavailable conversions are identified. The website cost calculator annualizes a single currency and does not perform currency conversion.

See the ECB’s disclaimer and reuse conditions. Neither the ECB nor Frankfurter endorses Atlas.

Merchant names and branding

Merchant and service names identify the subscriptions or transactions you track. Those names and any third-party marks belong to their respective owners. Atlas is not affiliated with or endorsed by those merchants merely because they appear in a record or guide.

Atlas branding identifies this product and its operator. We do not use a registered-trademark symbol for Atlas Budgeting.
