Privacy Policy
Last updated: August 17, 2026
DIZZUS GmbH ("we", "us", "Company"), with registered office in Zug, Switzerland, operates ConvertFly.io ("Service"). This Privacy Policy explains how we collect, use, and protect your personal data in compliance with the Swiss Federal Act on Data Protection (nFADP/nLPD) and, where applicable, the EU General Data Protection Regulation (GDPR).
1. Controller
The data controller is:
DIZZUS GmbH
Zug, Switzerland
Contact: convertfly.io/contact
2. Data We Collect
2.1 Account Data
When you create an account, we collect your email address, your name (if provided) and a password hash. Authentication is handled directly by ConvertFly; no third-party identity provider is involved.
2.2 Payment Data
Payment processing is handled entirely by Stripe. We do not store credit card numbers or bank account details. We receive your Stripe customer ID, subscription status, and transaction history.
2.3 File Data
Files you upload are processed automatically for conversion. We do not access, read, or analyze the content of your files. Uploaded files and conversion outputs are stored on storage systems operated by Dizzus GmbH and are automatically deleted:
- Import files: deleted immediately after conversion completes;
- Output files: deleted 24 hours after creation.
2.4 Usage Data
We collect technical data including IP address, browser type, operating system, pages visited, and conversion metadata (file formats, file sizes, timestamps). This data is used for analytics, debugging, and improving the Service.
2.5 API Data
If you use the ConvertFly API, we log API key identifiers, request timestamps, endpoints called, and response codes for rate limiting and abuse prevention.
3. Legal Basis for Processing
| Purpose | Legal Basis |
|---|---|
| Providing the Service (conversions) | Performance of contract (Art. 6(1)(b) GDPR / Art. 31(1) nFADP) |
| Payment processing | Performance of contract |
| Account management | Performance of contract |
| Analytics & service improvement | Legitimate interest (Art. 6(1)(f) GDPR / Art. 31(1) nFADP) |
| Security & fraud prevention | Legitimate interest |
| Legal compliance | Legal obligation (Art. 6(1)(c) GDPR) |
4. Third-Party Processors
We share personal data with the following processors, all of which have signed Data Processing Agreements:
| Provider | Purpose | Location |
|---|---|---|
| Dizzus GmbH (own infrastructure) | Application, database & conversion processing on dedicated servers operated by Dizzus | Canada (Montreal) |
| Dizzus GmbH (own infrastructure) | Temporary file storage & video processing (auto-deleted after 24h) | France |
| Dizzus GmbH (own infrastructure) | Self-hosted, cookieless web analytics (Plausible) | United Kingdom (London) |
| Stripe | Payment processing | USA (SCCs in place) |
| Cloudflare | DNS & bot protection (Turnstile captcha) | Global (SCCs in place) |
Authentication is handled directly by ConvertFly (no third-party identity provider). Files and conversion data never leave infrastructure operated by Dizzus GmbH.
5. International Data Transfers
Files and application data are processed on servers operated by Dizzus GmbH itself, located in Canada, France and the United Kingdom. All three are recognized by the Swiss FDPIC and the European Commission as providing an adequate level of data protection. Where a third-party processor is located in a country without such adequacy (e.g. Stripe or Cloudflare in the USA), we rely on Standard Contractual Clauses (SCCs) as safeguards under Art. 16(2) nFADP.
6. Data Retention
- Files: Import files deleted immediately after conversion; output files deleted after 24 hours.
- Account data: Retained as long as your account is active, then deleted within 30 days of account deletion.
- Payment records: Retained for 10 years as required by Swiss commercial law (OR Art. 958f).
- Usage logs: Retained for 90 days, then anonymized or deleted.
- API logs: Retained for 30 days.
7. Your Rights
Under the nFADP and GDPR, you have the right to:
- Access: Request a copy of your personal data;
- Rectification: Correct inaccurate data;
- Erasure: Request deletion of your data ("right to be forgotten");
- Portability: Receive your data in a machine-readable format;
- Restriction: Restrict processing in certain circumstances;
- Objection: Object to processing based on legitimate interest;
- Withdrawal of consent: Where processing is based on consent, withdraw at any time.
To exercise any of these rights, email our contact form. We will respond within 30 days.
8. Cookies & Tracking
ConvertFly uses essential cookies for authentication (session tokens) and functional purposes only. Web analytics are self-hosted (Plausible) on our own infrastructure: aggregated, privacy-friendly, and entirely cookieless.
We do not use advertising cookies or sell your data to third parties.
9. Children's Privacy
The Service is not intended for children under 16. We do not knowingly collect data from children. If you believe a child has provided us with personal data, contact us and we will delete it.
10. Security
We implement appropriate technical and organizational measures to protect your data, including TLS encryption in transit, encryption at rest for stored files (S3 SSE), HMAC-SHA256 signed worker communications, and regular security reviews.
11. Data Breach Notification
In the event of a personal data breach that poses a high risk to your rights and freedoms, we will notify the Swiss FDPIC and affected individuals without undue delay, in accordance with Art. 24 nFADP and Art. 33-34 GDPR.
12. Supervisory Authority
The competent supervisory authority is the Swiss Federal Data Protection and Information Commissioner (FDPIC). If you are located in the EU/EEA, you also have the right to lodge a complaint with your local data protection authority.
