Terms of Use

Last updated: June 10, 2026

1. Scope and provider

These terms of use govern use of the application Folanza ("the app"), reachable at app.folanza.app, as well as this informational page at folanza.app. The provider is:

Robert Dathe
Robert-Matzke-Str. 44
01127 Dresden, Germany
Email: admin@folanza.app

By using the app you agree to these terms. If you do not agree, please do not use the app.

2. What Folanza is — and what it is not

Folanza is a personal tool for recording and evaluating your own crypto transactions (coins and tokens). The app runs as a Progressive Web App in your device's browser; by default your data is stored exclusively on your device.

Folanza is expressly not financial, investment, tax or legal advice and no invitation to buy or sell assets. The app does not broker financial instruments, does not execute securities or crypto transactions and does not provide access to funds or wallets. All displays, key figures, charts and calculations serve solely your personal overview.

3. Risk notice and no advice

Investments in crypto assets involve substantial risks, up to and including total loss of the capital invested. Investment decisions are made at your own responsibility. Seek independent professional advice where appropriate.

Market and price data is obtained from external providers and may be delayed, incomplete or incorrect. The evaluations available in the app — including return, profit/loss and tax evaluations (such as holding-period status) — are non-binding aids without warranty and do not replace tax advice. Only the receipts from your exchanges/brokers and the findings of the tax authorities are authoritative. Verify all figures independently before using them (e.g. for your tax return).

4. Data storage and risk of data loss

Your inputs are stored locally in your browser's storage (LocalStorage) and only leave your device if you actively export them or set up an optional cloud backup or synchronization. Details are set out in the privacy policy.

You are responsible for backing up your own data. Local data can be lost, for instance by clearing browser data, switching device or browser, technical faults or browser-initiated cleanup.

If you enable the optional app lock (encryption): a forgotten password means the irretrievable loss of the encrypted data — there is no master key and no recovery option through the provider.

5. Permitted use

When using the app, you undertake:

  • to use the app only for your personal, non-commercial purposes;
  • not to violate any applicable laws and not to impair the rights of third parties;
  • not to tamper with the app, its source code or the server/proxy interfaces;
  • not to overload them automatically, circumvent them or misuse them for other purposes;
  • not to attempt to reverse-engineer the app or its underlying services, unless this is expressly permitted by law.

In case of violations, access to server-side functions (e.g. the data source proxies) may be restricted.

6. Availability, changes and cost

The app is currently provided free of charge and without a claim to any specific availability. It is under continuous development; features may change, be added or removed. Operation may be restricted, interrupted or discontinued at any time.

If paid features are offered in the future, separate, clearly labeled terms will apply — including statutory consumer information and the right of withdrawal.

7. Product lifecycle and availability

Sunset of the service. The provider is entitled to discontinue the app and the associated backend services for economic or technical reasons. A planned discontinuation will be announced with reasonable lead time — via a notice in the app as well as an information page. For compelling legal or security reasons operation may also be restricted at shorter notice.

Your data stays with you. Because Folanza keeps your data locally on your device, it is retained and exportable at any time even if the service is discontinued. Local portfolio tracking continues to work even after the server services are shut down; only online functions (such as fetching current prices) will no longer be available.

Statutory rights. Your mandatory statutory consumer rights — in particular any obligations to provide updates and continued provision for digital products under §§ 327 et seq. BGB (German Civil Code) and warranty rights — remain unaffected by the above provisions.

8. Third-party services

For certain functions the app uses services from third parties (including CoinGecko and other price providers, TradingView, Google, Microsoft, Dropbox, and — only if you explicitly enable them — read-only interfaces of individual exchanges). Those services are subject to their own terms of use and privacy notices. The provider has no influence on their content and availability.

9. Rights to the app

The app, its source code, its design as well as trademarks, logos and other content are protected by copyright and trademark law. You are granted a simple, non-exclusive, non-transferable right to use the app for its intended personal purpose. No further rights are transferred. You naturally remain the sole owner of the content you enter (your transaction data).

10. Liability

The provider has unlimited liability for damages arising from injury to life, body or health, from intent and gross negligence, and under the German Product Liability Act (ProdHaftG).

In case of slightly negligent breach of an essential contractual obligation (cardinal duty), the fulfillment of which is essential for the proper use of the app in the first place and on whose compliance you may regularly rely, liability is limited to the typical, foreseeable damage. Any liability beyond that is — insofar as permitted by law — excluded.

Subject to the preceding paragraphs: in particular, liability is excluded for the accuracy, completeness and timeliness of the market data obtained from third parties, for the results of calculations carried out in the app (including return and tax evaluations), for investment and other decisions you make on the basis of the app, and for the loss of locally stored data. Since the app is provided free of charge, liability is otherwise governed by statutory provisions.

11. Changes to these terms

These terms of use may be adapted to reflect changes in functionality or legal requirements. The version published at the time of use of the app applies. Please check this page occasionally.

12. Final provisions

German law applies, to the exclusion of the UN Convention on Contracts for the International Sale of Goods (CISG). Mandatory consumer- protection provisions of the state in which you have your habitual residence remain unaffected.

Should any provision of these terms be or become invalid, the validity of the remaining provisions remains unaffected.

The imprint and the privacy policy apply additionally.
