TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL DUONG THE BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, GOODWILL, OR BUSINESS INTERRUPTION, ARISING OUT OF OR RELATED TO YOUR USE OF THE APP.

OUR TOTAL AGGREGATE LIABILITY FOR ANY CLAIM ARISING OUT OF THESE TERMS OR THE APP WILL NOT EXCEED THE GREATER OF (A) USD 50 OR (B) THE AMOUNT YOU PAID US IN THE PAST 12 MONTHS (WHICH, FOR A FREE APP, IS ZERO).

Nothing in these Terms limits liability that cannot be limited under applicable law (e.g., gross negligence, wilful misconduct, or statutory consumer rights in the EU).

13. Indemnification

You agree to indemnify and hold harmless Duong The from any claim, loss, or expense (including reasonable attorneys' fees) arising from your breach of these Terms, your misuse of the App, or your violation of any law or third-party rights.
