SMS credits are sold as prepaid packs, non-refundable and without expiry, for the lifetime of the account. In case of payment default, access to the Service may be suspended after notification.
5. Personal data (GDPR / UK GDPR)
Processing of personal data in connection with the Service is described in our Privacy Policy . As a user of the Service, you act as data controller for your own clients' data stored in the Service (names, contact details, billing history); FastFaktura then acts as processor under the General Data Protection Regulation (GDPR). You warrant that you have a valid legal basis for sending invoices and reminders to your clients by email and SMS.
A Data Processing Agreement (DPA) governing FastFaktura's processing of your clients' data on your behalf is available on our Data Processing Agreement page and forms part of the contract when you use the Service.
6. Email and SMS communications — opt-out
Emails and SMS sent via the Service are strictly limited to transactional communications (invoices, reminders, payment links). Each recipient has an unsubscribe (opt-out) mechanism to stop receiving communications on a given channel. When a recipient exercises this right, the Service blocks further sends to that recipient on the relevant channel. You agree not to use the Service to send unsolicited commercial communications (spam) and to comply with applicable prospecting regulations.
7. Liability
FastFaktura uses reasonable means to ensure availability and security of the Service, without guaranteeing uninterrupted availability. FastFaktura shall not be liable for indirect damages, loss of revenue, data loss or reputational harm resulting from use or inability to use the Service. You remain solely responsible for invoice content, compliance with legal and tax obligations applicable to your business, and accuracy of data entered. FastFaktura's total liability, for any cause, is limited to amounts actually paid for the subscription in the preceding twelve months.
8. Termination
You may cancel your subscription at any time from your account; cancellation takes effect at the end of the current billing period, without pro-rata refund. FastFaktura may suspend or terminate an account for material breach of these Terms (including fraudulent use, spam or payment default), after notice and, unless urgent, a reasonable period to remedy the breach. After termination, you have 30 days to export your data, after which it is deleted in accordance with our privacy policy.
