When using an 20 application to interact with our Services, you are agreeing to our 21 Terms, so please read carefully. 22 23 24 Highlights: 25 ----------- 26 27 * You are responsible for selecting authentication methods and 28 policies that are adequate to protect your wallet key mappings. 29 Any losses arising from you not being able to satisfy the 30 selected authentication challenges or third parties being able 31 successfully pass the challenges are your problem. 32 33 * We will store your hashed account handle and allow clients to 34 query the associated Taler wallet key material. Our liability 35 will be limited to the liability limit exposed in the protocol. 36 37 * For our Services, we may charge various fees. The specific fee 38 structure is provided based on the TalDir protocol and should be 39 shown to you when you use an application to interact with our 40 services. You agree and understand that the TalDir protocol 41 allows for the fee structure to change. 42 43 * You agree to not intentionally overwhelm our systems with 44 requests and follow responsible disclosure if you find security 45 issues in our services. 46 47 * We cannot be held accountable for our Services not being 48 available due to circumstances beyond our control.
