Service description
Savvi provides: (a) document intake (email forwarding, uploads, photos); (b) automated extraction and enrichment (e.g., supplier details, contract dates, costs); (c) organisation by properties, suppliers, accounts and related folders; (d) alerts and workflow tools (e.g., contract end reminders, price comparisons/switching suggestions); (e) integrations you connect (e.g., accounting, property management, open banking read-access).
Savvi may offer beta or free features from time to time; such features are provided “as is” and may change or end at any time (see Section 14).
Account & eligibility
3.1 Business use. Savvi is designed for business and professional users (e.g., landlords, agents, service providers). If you use Savvi as a consumer, additional rights may apply under UK consumer law; see Section 18.
3.2 Registration. You must provide accurate information and keep credentials confidential. You are responsible for activity under your account.
3.3 Authorised users. You control who you invite. You are responsible for your users’ compliance with these Terms.
Customer Data & roles
4.1 Customer Data means documents, images, emails, transaction data and other content you or your users provide to Savvi.
4.2 Ownership. You retain all rights in Customer Data. You grant Savvi a licence to host, process and analyse Customer Data to provide the Service, improve detection quality, maintain security, and comply with law.
4.3 Controller/processor. For your account data and product telemetry, Savvi acts as an independent controller. For data you process through Savvi on behalf of your clients/tenants, Savvi acts as your processor. Our Data Processing Addendum (DPA) (Section 19) applies when we act as processor.

You will not: (a) break the law (including privacy, IP, spam/PECR rules); (b) upload malware; (c) reverse engineer, scrape, or overload the Service; (d) use the Service to make decisions that cause harm without appropriate human review; (e) misrepresent recommendations as professional advice.
Third-party services & integrations
Integrations (e.g., accounting, email, open banking, energy data) are provided by third parties under their own terms. We are not responsible for third-party services. You are responsible for connection permissions and ongoing access.

Free: up to 15 documents/month.
Pro: up to 1,000 documents/month, £10/month per workspace.

7.3 Trials & discounts. Trials and promotions may change or be withdrawn. We may adjust pricing on renewal with notice.
Accuracy, alerts & switching suggestions
8.1 Automation limits. Extraction and enrichment are probabilistic. You should verify key fields (e.g., contract dates, rates). Alerts may be delayed or missed due to supplier changes, document quality or third-party dependency.
8.2 Comparisons & offers. Switching suggestions are informational and may include affiliate links. Savings are estimates only and not guaranteed. You must check final tariffs/terms with the supplier.
Service levels & support
We aim for high availability but do not guarantee uninterrupted Service. Planned maintenance will be scheduled where feasible. Support is provided via legal@savvibills.com and in-app channels during UK business hours.

Compliance & lawful use
You confirm you have a lawful basis to process Customer Data. You will obtain necessary permissions and provide required notices to data subjects. You will comply with sector rules (e.g., property, utilities) and with PECR for any electronic marketing you conduct via integrations or exports.
Beta features
Beta features are for evaluation, may be unstable, and may be subject to additional terms. We may suspend or end betas at any time.

If you are a consumer (not using Savvi for your trade, business or profession): you may have a 14-day cancellation right from the date you sign up for a paid plan. By starting to use Savvi during the cancellation period you acknowledge that some rights may be affected. This Section does not limit your statutory rights.
