Privacy Policy

The controller of your personal data is Quantum Logic, Lda., tax number (NIPC) 516 651 560, registered office at Praceta da Tabaqueira A2, 1950-256 Lisbon, Portugal.

Contact for privacy questions and exercising your rights: geral@quantumlogic.pt.

• Contact and proposals: name, email, message and, if provided, phone number and type of space, to respond to your request and take pre-contractual steps (GDPR Art. 6(1)(b)). Fields marked as required are needed to respond; without them, you cannot submit the form.

• Contracts and invoicing: data needed to perform the contract and comply with legal duties, including tax and accounting requirements (Art. 6(1)(b) and (c)).

• Security: IP address and technical headers to prevent spam and abuse, based on our legitimate interest in protecting the website (Art. 6(1)(f)).

• Optional analytics: random identifier, visited pages, interactions, traffic source, approximate location, technical data, errors, masked recordings, test variant and rating responses, based on your consent (Art. 6(1)(a)). We do not collect contact form contents for analytics.

Contact enquiries are retained for up to 24 months; contractual, tax and accounting data for the applicable legal periods (generally 10 years); and analytics data for up to 30 days. These periods may be extended where needed to comply with a legal duty or establish, exercise or defend legal claims.

We use providers for hosting, transactional email (Resend), abuse prevention (Cloudflare), performance and analytics (PostHog, with analytics data hosted in the European Union). We may also disclose data to authorities where legally required. We do not sell your data.

Where a provider processes data outside the European Economic Area, we use an appropriate legal mechanism, such as an adequacy decision or the European Commission’s Standard Contractual Clauses.

We use strictly necessary storage to save language, theme and privacy choices and protect the form from spam. With consent, PostHog stores a random identifier and measures website use, including public-page recordings with fields and private content hidden, website variant tests and optional surveys. Forms and private portals are excluded from recordings. We do not use advertising or remarketing.

You can decline or withdraw consent at any time through “Privacy preferences” in the footer, without affecting your use of the website or the lawfulness of prior processing.

You may request access, rectification, erasure, restriction, portability or object to processing, and withdraw consent where applicable, by contacting geral@quantumlogic.pt.

You also have the right to lodge a complaint with the Portuguese Data Protection Authority (CNPD), Av. D. Carlos I, 134, 1.º, 1200-651 Lisbon, www.cnpd.pt.

We apply appropriate technical and organisational measures to protect personal data. We do not make solely automated decisions with legal or similarly significant effects; website variant allocation is used only to measure improvements.

We may update this Policy when our processing or the law changes. The current version is the one published on this page.
