licence. See the notices distributed with the Software.
5. NO WARRANTY
THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY

The Software stores the data you enter only on your device and does not send
it to the Author (see the Privacy Policy at https://varchenko.dev). You
decide what data to enter and who receives the PDFs you create, and you are
responsible for having the right to process your clients' data under the laws
that apply to you.
9. GOVERNING LAW
This licence is governed by the laws of Ukraine. Disputes are resolved by the
competent courts of Ukraine, without limiting any mandatory consumer rights
you have in your country of residence.
10. GENERAL
If a provision of this licence is held unenforceable, the rest remains in
effect. The Author may update this licence for new versions of the Software;
the version shown in the app applies to that version. This licence is the
entire agreement between you and the Author about the Software. If a
translation differs from the English text, the English text prevails.
