Privacy Policy

Last updated: October 1, 2026

1. Who we are

Rioko is a service operated by Kapta, a brand of ABSOLUTEPIXEL UNIPESSOAL, LDA, tax number (NIPC) 516277421, registered at Urbanização O Monte Lt1, Loja 11, 8200-428 Galé, Albufeira, Portugal. Rioko automates the issuing of tax documents from your sales platforms. For privacy matters, contact us at [email protected].

2. Data we collect

  • Account: name, email and unique identifier (via Clerk authentication).
  • Integration credentials: tokens, API keys and webhook secrets for the platforms you connect, used only to issue tax documents on your behalf.
  • Sales data: identifier, customer, tax number, amounts, products and statuses, processed to create the invoice or credit note.
  • Support requests: what you write in requests and in the Rioko Assistant chat, and the answers, kept in your account.
  • Technical logs: timestamps, request identifiers and external API responses, for auditing and diagnostics.

3. What we use it for

Data is used exclusively to:
  • Create Invoices, Invoice-Receipts and Credit Notes in your invoicing software automatically.
  • Ensure tax compliance (AT rules, VAT exemptions M01–M99, tax number).
  • Show history and reconciliation in the dashboard.
  • Send failure alerts and issuance reports.
  • Provide technical support when you request it, including through the Rioko Assistant (Roko), an artificial intelligence assistant that answers in the dashboard chat when you use it.

We do not sell or share your data with third parties for marketing purposes.

4. Subprocessors

To operate the service, we rely on:
  • Cloudflare (hosting, DNS, D1, KV, Workers) — EU/global.
  • Clerk (authentication) — EU/US.
  • Shopify, Stripe, Lodgify, EuPago (sales source platforms) — according to the connection you configure.
  • InvoiceXpress, Moloni, Vendus (tax document issuers) — Portugal.
  • Stripe (processing payments for your Rioko subscription) — EU/US.
  • Resend, with MailChannels as fallback (delivery of alert and report emails) — EU/US.
  • Fly.io (fixed-IP egress relay required by Lodgify) — EU.
  • Anthropic (artificial intelligence) — US. Used in two cases:
    • Automatic diagnosis attached to critical alerts: only a restricted, predefined set of fields (total and tax calculations, product and SKU names, the error text returned by the platform, and connection metadata). Customer name, email, tax number, order reference and user identifier are never sent in this case.
    • Rioko Assistant (Roko), in the dashboard chat once you accept it, and when the Rioko team asks it to look into one of your support requests: the request's messages, your connections' configuration (never credentials) and the data of the sales and documents it consults to answer, which may include your customers' name, email, tax number and order reference. The Assistant changes nothing in your account without your express approval.
    Under Anthropic's commercial terms, this data is not used to train models.
  • Google (Google Analytics 4 and Google Ads, measurement of traffic and of the ads that bring sign-ups) — EU/US, under the EU Standard Contractual Clauses. Loads only with your consent.

We use only the subprocessors required by the connection you configure. A platform you do not connect neither receives nor processes your data.

5. Retention

We keep your data while your account is active. Once the account is deleted, personal data is removed from our database within 30 days. Anonymised logs may be retained for up to 12 months for diagnostics and fraud prevention.

Tax documents already issued reside in your invoicing account and are not deleted by us: their retention follows the applicable legal archiving periods and is your responsibility.

6. Your rights (GDPR)

You have the right to:
  • Access your personal data.
  • Correct inaccurate data.
  • Request deletion ("right to be forgotten").
  • Data portability.
  • Withdraw consent at any time.
  • File a complaint with CNPD (Portuguese Data Protection Authority).

To exercise any right, email [email protected].

7. Security

All tokens and API keys are stored encrypted. Communications between Rioko and external services use HTTPS/TLS exclusively. Incoming webhooks are cryptographically verified (for example, HMAC-SHA256 in Shopify's case) before any processing. Access to data follows the need-to-know principle.

8. Cookies

Strictly necessary (always active, no consent needed): Clerk session — authentication; rioko_impersonate_id — admin impersonation only (1 day); rioko_attr — records signup origin (referrer/campaign) for abuse prevention (90 days).

Analytics and ad measurement (only with your consent): Google Analytics 4 — cookies _ga and _ga_* (~2 years) measure traffic; Google Ads — cookies _gcl_* (~90 days) record the click on a Rioko ad, so we know whether it led to a sign-up or subscription. Data may be processed by Google in the United States under the EU Standard Contractual Clauses. Loaded via Google Consent Mode v2 with everything denied by default — these cookies are set only after you accept.

You can change or withdraw your choice at any time via Cookie settings in the page footer. Your choice is stored locally on your device for 6 months, after which we ask again. We use no personalised advertising or remarketing cookies.

9. Changes

This policy may be updated. Material changes will be communicated by email to registered users at least 14 days before taking effect.
