How nodograph collects, uses, shares, and retains personal data.
Business information
Who controls your data
SIA VISCORBEL, trading as nodograph, is the controller for personal data collected through this site, support conversations, and purchase records we receive from Lemon Squeezy. Use the contact form for privacy questions or rights requests.
Personal data we process
- Contact form data: your name, email address, message, and any information you choose to include.
- Purchase and license data: purchase email, order reference, product, license status, refund records, tax or billing country, and support history.
- Payment data: payment card details are handled by Lemon Squeezy and its payment partners. Nodograph does not intentionally store full card numbers.
- Technical data: hosting, security, and email providers may process IP address, user agent, timestamps, delivery logs, and error logs.
Why we process it
- To answer questions and support requests, based on legitimate interests or pre-contract communication.
- To process purchases, deliver licenses, provide downloads, and handle refunds, based on contract performance.
- To maintain tax, accounting, fraud prevention, chargeback, and legal records, based on legal obligations and legitimate interests.
- To keep the site, contact form, email delivery, and software delivery reliable and secure, based on legitimate interests.
- To send marketing only if you opt in or where otherwise allowed by law. You can withdraw consent at any time.
Who receives it
We share personal data only as needed with service providers such as Lemon Squeezy, payment processors, checkout and license delivery providers, hosting providers, email providers, fraud and security tools, professional advisers, and public authorities where legally required.
Some providers may process data outside the EEA or UK. Where required, those transfers should rely on adequacy decisions, standard contractual clauses, or another lawful transfer mechanism.
Retention
Support messages are kept for as long as needed to resolve the request and normally no longer than 24 months after the last related contact. Purchase, tax, refund, license, accounting, and dispute records may be kept for up to 7 years or longer if required by law or needed for an active dispute. Security logs are kept for the period needed to protect the service.
Your rights
Depending on your location, you may have rights to access, correct, erase, restrict, object to, or receive a copy of your personal data. You may also withdraw consent where processing is based on consent and lodge a complaint with your local data protection authority.
