Privacy policy
HelvetData places the highest importance on the protection of your personal data. This policy describes, in full transparency, the processing carried out, the legal bases, the retention periods, your rights and our subprocessors. It applies jointly to the revised Swiss Federal Act on Data Protection (revFADP, in force since 1 September 2023) and to the European General Data Protection Regulation (GDPR).
Last updated · 14 May 2026
Data controller
The controller of personal data within the meaning of the revFADP and the GDPR is:
- EMVEE VENTURES LTD
- 71-75 Shelton Street, Covent Garden
- London WC2H 9JQ, United Kingdom
Operations managed and operated from Switzerland. General contact · hello@helvetdata.ch Data protection · privacy@helvetdata.ch
No formal Data Protection Officer (DPO) has been designated at this stage. EMVEE VENTURES LTD assumes that role by delegation. Given the nature of processing (data from public registers, B2B, no special categories) and the absence of employees, the designation of a DPO is not mandatory under art. 10 revFADP.
Personal data collected
HelvetData collects the following categories of data:
- Account data: email address, password (hashed with bcrypt, never stored in clear), full name (optional), preferred language.
- Usage data: saved views, filters, watchlists, API tokens, search history.
- Billing data: name, company name, billing address, VAT number where applicable. Card data is never stored by HelvetData and is handled exclusively by Stripe.
- Technical data: IP address, browser type, operating system, access logs (90-day rotation).

No category of so-called «special» personal data within the meaning of art. 5 let. c revFADP (health, religion, political opinions, genetic or biometric data) is processed by HelvetData. Only data published in a professional and commercial context are collected.
Legal basis and data from public registers
A significant part of the Data published by HelvetData comes from official Swiss public registers. HelvetData confirms their public nature, legal origin and the legal basis for processing.
Official public sources used:
- Cantonal building-permit publications (cantonal official gazettes, art. 33 et seq. of the cantonal building laws);
- Swiss Commercial Register (art. 928 CC and Commercial Register Ordinance);
- Public phone and address directories pursuant to art. 8 of EU Regulation 2018/1807 and the Swiss Telecommunications Act;
- Swiss official commercial publications, public tenders, the trademark register, cantonal debt-enforcement and bankruptcy registers.
Primary legal basis: art. 31 para. 2 let. e revFADP («processing necessary for the safeguarding of the overriding legitimate interests of the controller or a third party») combined, for data subjects residing in the EU, with art. 6 para. 1 let. f GDPR («legitimate interest of the controller or a third party»).
Balancing of interests (proportionality test):
- HelvetData provides a B2B commercial intelligence service that aggregates exclusively data lawfully published by Swiss authorities;
- The recipients are professionals (craftsmen, agencies, lawyers, fiduciaries, M&A advisors, family offices) whose legitimate interest in identifying commercial and legal opportunities is manifest;
- The reasonable expectation of the data subject, once published in a cantonal official gazette or the Commercial Register, is that the information may be consulted and used by professional actors;
- HelvetData applies systematic data minimization (name, canton, public reference only), an internal `is_personal_data=true` flag, a 24-hour opt-out registry, and provides simple access to data subject rights at privacy@helvetdata.ch.
Data subject rights: in accordance with art. 25 (right of access), art. 28 (right to data portability), art. 30 (right to object), art. 32 (right to rectification and erasure) revFADP, any data subject may exercise their rights by writing to privacy@helvetdata.ch. A response is provided within a maximum of thirty (30) days.
No automated individual decisions: within the meaning of art. 21 revFADP, HelvetData does not take any automated individual decisions producing legal effects or significantly affecting a person. The algorithmic scores (momentum, distress, expansion) are informational for the Customer, who remains free to make their commercial decision. A human is always in the loop.
Retention: building-permit publications are retained for three (3) years from publication; business contact details enriched via public sources are retained for twelve (12) months from the last enrichment, unless renewed. Deletion may be requested at any time via privacy@helvetdata.ch and is effective within 24 hours.
