Privacy Policy

Enhanced Computing Solutions, trading as "Signatura" ("we", "us", "our"), provides email signature management for Microsoft 365 and Google Workspace organizations. This policy explains what we collect, why, and how you can control it.

Who is responsible for your data

Enhanced Computing Solutions is the data controller for personal data described in this policy, and determines the purposes and means of processing it. Where we process directory or mailbox data belonging to a customer's organization, we act as a processor on that customer's instructions. You can contact us at support@signatura-us.com.

Information we collect

• Account data. Name, work email, company name, account type (direct or partner), and authentication identifiers.
• Directory data. When you connect a mail platform, we read user profile attributes (name, title, email, phone, department, photo) needed to render signatures, and we write signature settings to mailboxes you designate.
• Content you create. Signature templates, assignment rules, tenant configuration, and invitations.
• Billing data. Subscription plan, mailbox quantity, and payment status. Card details are collected and processed by Paddle.com, our Merchant of Record — we never see or store full card numbers.
• Operational data. Audit logs (actor, action, timestamp), error logs, and basic usage/diagnostic information.

How we use information

• To deliver, secure, and support the service.
• To synchronize and enforce signatures on mailboxes you authorize.
• To process payments, subscriptions, refunds, invoices, and sales tax/VAT compliance via Paddle.com, our Merchant of Record.
• To send transactional messages (invites, receipts, service notices).
• To detect abuse, troubleshoot, and meet legal obligations.

We do not sell personal data and we do not use customer data to train AI models.

Legal basis for processing

Where the UK GDPR, EU GDPR, or similar laws apply, we rely on the following legal bases:

• Performance of a contract — creating and administering your account, connecting tenants, rendering and applying signatures, and providing support.
• Legitimate interests — securing the service, preventing fraud and abuse, maintaining audit logs, and improving reliability and features, balanced against your rights.
• Legal obligation — retaining financial and tax records and responding to lawful requests.
• Consent — optional communications such as product updates, which you may withdraw at any time.

Tenant isolation

Each customer organization is a separate tenant. Access is enforced at the database layer so users can only read or modify data belonging to tenants they are members of. Partner accounts can access only the client tenants they own.

Sharing

We share data only with service providers acting on our behalf: cloud hosting and database infrastructure, Paddle.com (Merchant of Record: payments, subscription management, tax compliance, invoicing), Microsoft and Google (only the APIs of the tenant you connect), and email delivery. We may disclose information if legally required, or as part of a merger or acquisition, with notice where required.

Retention

We retain account, template, and audit data while your subscription is active. After cancellation, data is retained for a limited wind-down period and then deleted or anonymized, except where longer retention is legally required (e.g. financial records). You can request deletion at any time.

Security

Data is encrypted in transit and at rest. Platform credentials and tokens are stored encrypted and are used only to perform the actions you authorize. Access to production systems is limited to personnel who need it.

International transfers

Our infrastructure and subprocessors may process data in the United States and other countries. Where required, transfers rely on Standard Contractual Clauses or another lawful mechanism.

Your rights

Depending on your location, you may request access, correction, deletion, export, or restriction of your personal data, and may object to certain processing. Contact us at support@signatura-us.com and we will respond within the timeframe required by law.

Cookies

We use strictly necessary cookies and local storage for authentication and session management. We do not use advertising cookies.

Children

The service is for business use and is not directed to anyone under 16.

Changes

We will post updates to this page and, for material changes, notify account administrators by email.
