Privacy notice

Updated: 17 September 2026

Who handles your information

Valerica-Claudiu Dau, trading as ClauTools, is responsible for personal information used to operate your ClauTools account and subscription. Contact claudiu0092@gmail.com or write to 12 Aberdare Road, Northampton, NN5 7DA, United Kingdom.

Information we use

• Account: your email, account identifier, sign-in and session information. Supabase provides email-code sign-in and account storage.
• Invoices you create: the business and customer details, line items, amounts and logo you enter. A draft is held in your browser tab. When you request a preview or PDF, those details are sent to our server to render it. The application does not save these invoice contents in its database or send them to your customers. Downloaded files remain wherever you save them.
• Subscriptions: your email, Stripe customer and subscription references, plan, status, relevant dates and the terms accepted. Stripe receives billing addresses and payment information directly. Our application does not receive or store your full card number or CVC.
• Support: your account email, messages, replies and read markers. Messages are stored in the app and can be read by authorised support staff. Email support is handled through Gmail; in-app messages are not automatically forwarded there.
• Technical records: hosting, authentication, security and payment providers may process IP addresses, device/browser information and request logs needed to operate and protect the service.

Why we use it

We use account, subscription and support information to provide and administer the service you request, under our contract with you. Where an organisation is the customer, our legitimate interest is providing and supporting that organisation's account. We use limited technical records to keep the service secure and diagnose faults, and retain payment records where needed to meet legal accounting obligations. We process the invoice details you submit to fulfil your rendering request; you remain responsible for having authority to use your customers' details.

We do not sell personal information or use invoice contents for advertising. The application has no advertising pixels or marketing analytics. An email and the requested payment details are needed to sign in and subscribe; without them we cannot provide those features.

Providers and processing locations

ClauTools uses Supabase for authentication, database storage and PDF processing, Stripe for payments and fraud checks, and the OpenAI Sites hosting service and its infrastructure providers to deliver the website. Your browser also loads the Supabase software library from jsDelivr. Gmail processes support emails you send to our contact address.

These providers may process information outside the UK. Their data-processing terms describe applicable locations and transfer protections, including adequacy arrangements or standard contractual safeguards where required. Contact us for information about the arrangements relevant to your data. See Supabase privacy, Stripe privacy, OpenAI privacy and Google privacy.

Storage and retention

We retain account information while your account is needed to provide the service. Support history is retained as needed to resolve enquiries and associated disputes. Payment and contract records may be retained after account closure where required for accounting, legal claims or fraud prevention. Retention depends on those obligations and the nature of the record; contact us for a deletion review.

Sign-in information is stored in your browser so you can stay signed in. Invoice drafts use tab-specific session storage and are cleared by the app when you log out. Closing the tab normally ends that draft session; browser restore features may retain it. We do not provide a permanent invoice archive. Payment and authentication providers may also use their own essential security storage.

Payment checks

Stripe uses automated checks to help assess payments. Our UK-only rule rejects payments if the billing-address country is outside the UK or missing. Subscription status determines access to clean PDF downloads. Contact us if you believe a payment or access decision is incorrect so that we can review the issue.

Your choices and rights

Depending on the circumstances, you can request access, correction, deletion, restriction or a portable copy of your personal information. You may object to processing based on legitimate interests. Contact our email above to exercise your rights or request account closure. Cancelling a subscription stops renewal; it does not automatically delete your account. We may need to verify your identity, and some records must be retained despite a deletion request.

You can complain to the UK Information Commissioner's Office at ico.org.uk/make-a-complaint. We update this notice when our handling of information changes and will bring material changes to your attention.
