2. Scope

This Privacy Policy applies to all personal data processed through mirismartguard.com. It covers two categories of data subjects: registered users who create a profile ("Owners"), and visitors who scan a QR code linked to the Service ("Visitors"). Visitors are data subjects — data about their scan is collected as described in §3.2 and §3.4.

3. Data We Collect and How

3.1 — Registered Users (Owners)

3.1a — Phone number: how it is used

Your phone number is stored encrypted (AES-256) and is used for one purpose: to open a WhatsApp conversation when a visitor chooses to contact you. It is not shown on your profile page and is not contained in the page or its HTML source, so a visitor who only looks at the page does not receive it.

When a visitor taps the WhatsApp button, our server redirects their device to WhatsApp using your number. From that moment the number is known to that visitor and to WhatsApp — this is how the contact works, and it cannot work otherwise. You can switch the WhatsApp button off at any time in your dashboard.

3.2 — Visitors (non-registered)

Visitors who scan a QR code are data subjects. The following data is collected at the time of a scan:

DataFormat storedPurpose
Name (if voluntarily submitted)Plain textScan notification to Owner
IP addressHMAC-SHA256 hash — plain IP not storedFraud prevention, rate limiting

Visitors may request access to or deletion of their data by contacting privacy@mirismartguard.com.

3.3 — Waitlist Subscribers (pre-launch)

DataPurposeRetentionLegal basis
Waitlist email (optional)Launch announcement, product updatesUntil launch + 6 months, or until unsubscribeConsent (nFADP Art. 6.6 / GDPR Art. 6(1)(a))

Waitlist subscribers may unsubscribe at any time by contacting contact@mirismartguard.com. For the complete list of parties who may process your data, see §7.

3.4 — Scan Logs (every QR code scan)

Device typeCategory (mobile/tablet/desktop/bot)12 months
User-agent stringTruncated to 500 characters12 months
Whether scan was blockedBoolean12 months

4. What We Do NOT Collect

  • We do not store IP addresses in plain text — only as HMAC-SHA256 hashes.
  • We do not sell, rent, or trade personal data. Authorised delivery partners may confirm a delivery scan via our API — they receive only the recipient's name and QR serial, not phone numbers or addresses.
  • We do not use data for advertising or profiling.
  • We do not use third-party analytics tools (no Google Analytics, no Meta Pixel).

5. Legal Basis for Processing

6. Technical Measures

  • AES-256-CBC with a random IV per encryption operation for all phone numbers
  • HMAC-SHA256 for IP address and phone hashing — computationally irreversible
  • Row-Level Security (RLS) enforced at the database level
  • Service role access restricted to server-side API routes only
  • Signed session cookies (httpOnly, Secure, SameSite=Strict) — cannot be read by JavaScript
  • All data in transit transmitted via HTTPS/TLS

7. Data Sharing and Sub-processors

We do not sell data. The following parties receive personal data solely to operate the Service. This is the complete list — it applies to all data categories described in §3.

Sub-processorRoleData receivedProcessing locationSafeguard
SupabaseDatabase, authenticationAll profile data, scan logs, waitlist emailsEU — Ireland (eu-west-1)SCCs

Core storage and processing (Supabase, Vercel) takes place within the European Union. Transfers to the United States (Stripe, Resend) are governed by Standard Contractual Clauses approved by the European Commission (Art. 46 GDPR / Art. 16 nDSG). Telegram and WhatsApp operate under their own terms; the Service only initiates the contact — it does not transmit or store message content.

8. Data Retention

CategoryRetention period
Owner account dataUntil account deletion + 30-day grace period
Scan logs12 months from scan date
IP rate-limiting records30 days after block expires
Payment records10 years (Swiss accounting law — Art. 958f CO)
Abuse reportsUntil resolved + 6 months
Visitor data (name)12 months from last scan, then anonymised automatically
Transfer tokens48 hours (auto-expired)
Waitlist emailUntil launch + 6 months, or until unsubscribe request

9. Your Rights

Under nDSG (Art. 25–27) and GDPR (Art. 15–22), you have the following rights:

RightDescription
AccessRequest a copy of all personal data held about you
RectificationCorrect inaccurate or incomplete data
ErasureRequest deletion of your data (“right to be forgotten”)
RestrictionRequest temporary suspension of processing
PortabilityReceive your data in a machine-readable format

To exercise any of these rights: privacy@mirismartguard.com

10. Right to Lodge a Complaint

If you believe your data protection rights have been violated, you may lodge a complaint with:

Federal Data Protection and Information Commissioner (FDPIC / PFPDT)
Feldeggweg 1, CH-3003 Bern
www.edoeb.admin.ch

EU residents may also contact their local Data Protection Authority.

11. Automated Decision-Making

The Service uses automated rate-limiting logic to detect and block abusive scanning behavior based solely on hashed IP activity patterns. This does not involve profiling of personal characteristics. Blocked users may contact the Operator to dispute a block.

12. Children's Data

The Service is not directed at persons under 16 years of age. We do not knowingly collect personal data from minors. If we become aware that a minor has submitted personal data, it will be deleted immediately.

13. Cookies

The Service uses a single signed session cookie (httpOnly, Secure, SameSite=Strict) strictly necessary for visitor identification. No advertising, tracking, or analytics cookies are used.

14. Changes to This Policy

This Privacy Policy may be updated periodically. The "Effective date" at the top reflects the most recent revision. Registered users will be notified of material changes via email. Continued use of the Service constitutes acceptance.
