These Terms ("Terms") are a legal agreement between you and NoesisBit (Borja Castellano-Extremadouro, a sole proprietor registered in Washington, USA — UBI 606240494) ("Zaisei", "we", "us") governing your use of the Zaisei mobile application and related services (the "Service"). By creating an account or using the Service, you agree to these Terms. If you do not agree, do not use the Service.
We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the Service on devices you own or control, for your personal, non-commercial use, subject to these Terms and the app store's terms.
You must be at least 18 years old. You are responsible for keeping your login credentials and device secure and for all activity under your account. Notify us promptly of any unauthorised use.
Zaisei aggregates and displays information about your accounts, holdings and properties. It does not provide financial, investment, tax, accounting or legal advice, and nothing in the Service is a recommendation to buy, sell or hold any asset. You are solely responsible for your financial decisions.
Account balances, transactions, holdings, market quotes, exchange rates and property valuations come from third parties (including Plaid, Powens, Finnhub, mapping and valuation providers). This data may be delayed, incomplete, estimated or inaccurate. Market prices are not real-time trading data. Property values are estimates. We do not guarantee the accuracy, completeness or timeliness of any data, and you should not rely on it for time-sensitive or high-stakes decisions.
You agree not to: (a) access accounts or data you are not authorised to; (b) reverse engineer, scrape or disrupt the Service; (c) use it unlawfully or to infringe others' rights; or (d) circumvent security or usage limits. The read-only sharing feature is for sharing your own data with people you trust; you are responsible for who you share it with.
You retain ownership of the data you provide (e.g. properties). You grant us the limited rights needed to operate the Service for you, as described in the Privacy Policy.
You may stop using the Service and delete your account at any time from Profile → Delete account, which permanently removes your data as described in the Data Retention & Disposal Policy. We may suspend or terminate access if you breach these Terms or to protect the Service.
The Service is provided "as is" and "as available", without warranties of any kind, whether express or implied, including merchantability, fitness for a particular purpose and non-infringement. We do not warrant that the Service will be uninterrupted, secure or error-free.
To the maximum extent permitted by law, Zaisei and its suppliers will not be liable for any indirect, incidental, special, consequential or punitive damages, or any loss of profits, data or goodwill, arising from your use of (or inability to use) the Service. Our total liability for any claim is limited to the amount you paid us for the Service in the 12 months before the claim (or, if the Service is free, a nominal amount). Some jurisdictions do not allow certain limitations, so some may not apply to you.
We may update these Terms. Material changes will be notified in the app; continued use after changes take effect constitutes acceptance.
These Terms are governed by the laws of the State of Washington, United States, without regard to conflict-of-laws rules, and disputes are subject to the courts of that jurisdiction, unless mandatory local law provides otherwise.
