Terms of Service
Last updated: November 9, 2026
These Terms of Service ("Terms") govern your access to and use of the ConvertFly platform ("Service"), operated by DIZZUS GmbH, a company incorporated under Swiss law with its registered office in Zug, Switzerland ("we", "us", "Company").
By accessing or using the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.
1. Service Description
ConvertFly is a cloud-based file conversion service. Users can convert files between the formats listed on the website via the web interface or REST API. Converted files are stored temporarily and automatically deleted 24 hours after creation.
2. Accounts & Registration
You can use the Service without an account, within the free tier in force (currently 10 conversions per day). To access paid features, the API or higher limits, you must create an account (e-mail address and password).
You are responsible for maintaining the confidentiality of your account credentials and for all activity under your account. You must notify us immediately of any unauthorized use.
3. Conclusion of the contract
A purchase is concluded in four steps:
- you choose a package or a subscription on the Pricing page;
- the “Confirm your purchase” page summarises the offer and the price; there you request immediate performance and can go back to the offers to change your choice;
- on Stripe’s secure payment page, you enter and can correct your billing address, your VAT number if any and your payment method, then you click the payment button, which constitutes a firm order;
- we confirm the order without delay by e-mail to your account address, and the invoice is available in your dashboard.
The contract consists of these Terms in the version in force on the day of the order; we recommend that you save them. You must be at least 16 years old to create an account and, if you are a minor, have the consent of your legal representative for any purchase.
4. Credits & Pricing
The Service uses a credit-based pricing model. Credits are consumed per conversion operation. Credit costs vary by conversion type (see Pricing for details).
- Packages: One-time credit purchases. Package credits do not expire.
- Subscriptions: Monthly credit allocations. Subscription credits reset each billing cycle and do not roll over.
- Free tier: a number of free conversions per day, without an account (currently 10). Its content and limits may change.
We may change our offers at any time: create, modify or withdraw packages and subscriptions, change prices, the number of credits granted, the credit cost of a conversion, file sizes and limits, and the content of the free tier (number of conversions, formats, file size). Package credits already purchased remain usable. For an ongoing subscription, a change of price or allowance takes effect at the next renewal, after notice by e-mail or on the Service; you may stop the renewal before that date.
All prices are displayed in USD. Payments are processed securely by Stripe. All sales are final, no refunds are issued for unused credits except where required by applicable law.
Taxes and availability. Prices include Swiss VAT (8.1%) for customers in Switzerland and Liechtenstein. Paid plans and credit packs are sold to consumers in Switzerland, Liechtenstein, the European Union, the United Kingdom, United States, Canada, Australia, New Zealand, Norway, Iceland, Singapore, Malaysia, Thailand, Japan, Indonesia, Mexico, Brazil, Argentina, Chile, Colombia, Peru, Ecuador, Bolivia, Paraguay, Uruguay, Costa Rica, Panama, Guatemala, Honduras, El Salvador, Nicaragua, Dominican Republic and Puerto Rico; elsewhere, they are sold only to businesses that provide a valid VAT number, under the reverse charge mechanism. The country is established from the billing address and the country of the payment card; a purchase that does not meet these conditions is cancelled and refunded in full, and no credits are added. Invoices are issued by DIZZUS GmbH, VAT No. CHE-469.903.322 MWST.
Right of withdrawal. Credits and subscriptions are digital services delivered immediately after payment. Before paying, you are asked to expressly request immediate access and to acknowledge that you thereby lose any statutory right of withdrawal (for consumers in the European Union, Art. 16(m) of Directive 2011/83/EU). A purchase cannot be completed without this confirmation, which is recorded with the payment.
5. Acceptable Use
You agree not to:
- Upload files that contain malware, viruses, or malicious code;
- Use the Service for illegal purposes or to process illegal content;
- Attempt to circumvent rate limits, authentication, or security mechanisms;
- Reverse engineer, decompile, or disassemble the Service;
- Resell or redistribute the Service without our written consent;
- Use automated means to abuse the free tier or create multiple accounts to circumvent limits.
We reserve the right to suspend or terminate accounts that violate these Terms without prior notice.
6. File Handling & Data Retention
Files uploaded to ConvertFly are processed on dedicated infrastructure operated by Dizzus GmbH (United Kingdom and France). Uploaded files and conversion outputs are stored temporarily on our own storage systems and automatically deleted 24 hours after creation. Import files are deleted immediately after the conversion completes.
Files are processed automatically by the conversion software. Their content is used for the conversion only and is not shared.
7. API Usage
Paid accounts can access the ConvertFly API with API keys generated in the dashboard. API use is subject to rate limits. You are responsible for the security of your API keys; we are not liable for unauthorised use of your keys resulting from a lack of care on your part.
8. Intellectual Property
You retain all rights to the files you upload. We claim no ownership or license over your content. The ConvertFly name, logo, and Service are the property of DIZZUS GmbH.
9. Service Availability
We strive for high availability but do not guarantee uninterrupted service. We may carry out maintenance, updates or changes that temporarily affect availability.
10. Limitation of Liability
Our liability is unlimited in case of wilful misconduct or gross negligence, and for personal injury. Otherwise, it is excluded for indirect and consequential damage, in particular loss of profit and loss of data not resulting from gross negligence on our part.
For direct damage caused by slight negligence, our liability is limited to the amount you paid us in the 12 months preceding the event giving rise to the damage.
Liability for auxiliaries (art. 101 Swiss Code of Obligations) is excluded to the same extent.
11. Termination
You may stop using the Service at any time. You can delete your account yourself from the settings of your dashboard: a confirmation e-mail is sent to you, and the deletion takes place only after you follow the link it contains. We may suspend or terminate your access if you breach these Terms, or for any other reason with 30 days’ notice for paid accounts.
You can stop the automatic renewal of your subscription at any time from your dashboard or the billing portal. The subscription then stays active until the end of the period already paid, and ends with no further charge. Deleting the account cancels any ongoing subscription immediately.
If you delete your account, or if we close it for a breach of these Terms, your files, API keys and history are erased, remaining credits (packages and subscription) are lost and no refund is granted, not even pro rata for the current period, unless mandatory law provides otherwise. If we end the Service or your account for any other reason, we refund the purchase value of unused package credits and the part of the subscription corresponding to the unexpired period.
12. Modifications
We may update these Terms at any time. Material changes will be communicated via email or a notice on the Service. Continued use after changes constitutes acceptance of the revised Terms.
13. Governing Law & Jurisdiction
These Terms are governed by the laws of Switzerland. Any disputes shall be submitted to the exclusive jurisdiction of the courts of Zug, Switzerland, unless mandatory consumer protection laws of your country of residence provide otherwise.
