Terms of Service

PDFUnlock ("the Service") is operated by INTEK CENTER SASU, a simplified joint-stock company (société par actions simplifiée unipersonnelle) registered at 369Q Avenue de Verdun, 33700 Mérignac, France. RCS Bordeaux 844 849 174. Intra-community VAT: FR02844849174.

In accordance with Article 6 of French Law No. 2004-575 of 21 June 2004 ("LCEN"), the publication director is the company's president.

By using the Service, you ("the User") accept these Terms unconditionally. If you do not agree, you must not use the Service.

• Service: The PDFUnlock web application accessible at pdfunlock.app, including all features, APIs and related services.
• Company: INTEK CENTER SASU, as identified in Article 1.
• User: Any natural or legal person who accesses or uses the Service.
• Job: A password recovery task initiated by uploading a PDF file to the Service.
• Password: The user password (opening password) or owner password (permissions password) of a PDF file.
• Deep Recovery: The paid GPU-accelerated password cracking service.
• Owner Removal: The free service that removes editing/printing restrictions from a PDF.

PDFUnlock provides two distinct services:

• Owner Password Removal (Free): Instant removal of editing, printing and copying restrictions from PDF files. This service is free, requires no account and produces an unlocked copy of the PDF.
• User Password Recovery (Paid): GPU-accelerated recovery of the opening password of encrypted PDF files. This service uses dictionary attacks, rule-based mutations and brute-force techniques. Payment is collected only if the password is successfully recovered (pay-on-success model).

The Service supports all standard PDF encryption types: RC4-40, RC4-128, AES-128 and AES-256.

Account creation is optional. The free owner-removal service requires no registration. For paid password recovery, only an email address is required for job completion notifications.

If you create an account, you are responsible for:

• Maintaining the confidentiality of your login credentials.
• All activities that occur under your account.
• Notifying us immediately at the in-app support form of any unauthorized access.

We reserve the right to suspend or terminate accounts that violate these Terms.

Prices are displayed in EUR, inclusive of applicable VAT calculated based on the User's country (EU VAT OSS regime). For non-EUR payment methods, Stripe converts the amount at the prevailing exchange rate. The exact amount charged is displayed at checkout before payment confirmation.

An invoice is generated automatically for every paid transaction and is available in the User's dashboard. Invoices comply with Article 289 of the French Code général des impôts and contain all legally required information (sequential number, date, seller and buyer identification, description, VAT breakdown, total).

The User is charged only after the password has been successfully recovered. If the Service cannot recover the password, the User owes nothing and no payment method is charged.

The payment flow works as follows:

1. The Service attempts to recover the password.
2. If the password is found, the User is presented with the option to pay and reveal it.
3. Payment is processed via Stripe Checkout. The password is revealed immediately upon successful payment.
4. If the password is not found within 24 hours, the Job is marked as failed and the User pays nothing.

In accordance with Article L221-28 13° of the French Code de la consommation and Article 16(m) of EU Directive 2011/83/EU, the right of withdrawal does not apply to this Service.

The Service delivers a fully personalized digital content (a recovered password unique to the User's specific PDF file) that is supplied immediately upon payment. Before completing the purchase, the User expressly acknowledges that:

• The digital content is personalized and cannot be standardized.
• Performance of the Service begins immediately upon payment.
• The User waives the 14-day withdrawal right as a consequence.

This exclusion is consistent with the interpretation of the Court of Justice of the European Union (CJEU) regarding personalized digital services.

Given the pay-on-success model, the User's primary guarantee is that no payment is collected unless the password is found. This provides inherent consumer protection.

Refunds are not a contractual right but a voluntary goodwill gesture. If the recovered password does not open the User's PDF file:

1. Contact the in-app support form within 7 days of payment, providing the Job ID and a description of the issue.
2. Our support team will verify the password against the original file.
3. If confirmed defective, a full refund is issued via the original payment method within 14 business days.

By uploading a PDF file to the Service, the User certifies and warrants that:

• The User is the legitimate owner of the file, or has obtained explicit written authorization from its owner to recover the password.
• The use of the Service does not violate any applicable law, third-party right or contractual obligation.
• The file does not contain illegal content.

The Company is not responsible for verifying the User's right to access the file. The User assumes full legal responsibility for any unauthorized use of the Service.

The User agrees not to:

• Use the Service for any unlawful purpose, including recovering passwords on files the User does not own or have authorization to access.
• Attempt to reverse-engineer, decompile, disassemble or otherwise extract the source code of the Service.
• Use automated tools (bots, scrapers, scripts) to interact with the Service without prior written authorization.
• Circumvent rate limiting, authentication or security measures.
• Upload files containing malware, viruses or malicious code.
• Resell, sublicense or redistribute the Service or its outputs.

All elements of the Service — including but not limited to source code, algorithms, user interface, design, trademarks, logos, text and documentation — are the exclusive property of the Company or its licensors and are protected by French and international intellectual property laws.

The User is granted a limited, non-exclusive, non-transferable, revocable license to use the Service in accordance with these Terms. This license does not confer any ownership rights.

Obligation of means: The Service constitutes an obligation of means (obligation de moyens), not of result (obligation de résultat). The Company commits to deploying reasonable technical efforts to recover PDF passwords but does not guarantee success. Some passwords — especially those using AES-256 encryption with strong random strings — may be technically unrecoverable.

The estimated success rate displayed before initiating a Deep Recovery is indicative and not binding.

Liability cap: The Company's aggregate liability for any and all claims arising from or related to the Service is limited to the total amount paid by the User to the Company in the 12 months preceding the event giving rise to the claim.

Exclusions: The Company shall not be liable for:

• Indirect, incidental, special, consequential or punitive damages.
• Loss of data, revenue, profits, business opportunities or goodwill.
• Damages arising from force majeure, third-party service outages (Stripe, Google Cloud, SendGrid) or circumstances beyond the Company's reasonable control.
• Use of the Service in violation of these Terms or applicable law.

The User agrees to indemnify, defend and hold harmless the Company, its officers, directors, employees, agents and affiliates from and against any and all claims, damages, losses, liabilities, costs and expenses (including reasonable attorney's fees) arising from or related to:

• The User's use of the Service.
• The User's violation of these Terms.
• The User's violation of any applicable law or third-party right.
• Any claim that the User did not have authorization to recover the password of an uploaded file.

The collection and processing of personal data in connection with the Service is governed by our Privacy Policy, which forms an integral part of these Terms.

By using the Service, you acknowledge that you have read and understood the Privacy Policy.

By the User: You may stop using the Service at any time. If you have an account, you may request its deletion by contacting the in-app support form. Upon deletion, all personal data will be removed in accordance with the retention periods described in the Privacy Policy (invoices are retained for 10 years per legal requirement).

By the Company: We may suspend or terminate access to the Service, with or without notice, if:

• The User violates these Terms.
• The User engages in fraudulent, abusive or illegal activity.
• Required by law or court order.

Termination does not affect any rights or obligations accrued prior to termination.

The Company reserves the right to modify these Terms at any time. The updated version will be published on this page with a new "Last updated" date.

For material changes that affect the User's rights or obligations, we will notify registered users by email at least 15 days before the changes take effect. Continued use of the Service after the effective date constitutes acceptance of the modified Terms.

These Terms are governed by and construed in accordance with French law.

Dispute resolution escalation:

1. Amicable resolution: The parties agree to first attempt to resolve any dispute amicably by contacting the in-app support form. The Company commits to responding within 30 days.
2. Mediation: If an amicable resolution cannot be reached, the User may refer the dispute to the consumer mediation service of the CNIL or to any accredited mediator listed by the European Commission's Online Dispute Resolution platform.
3. Jurisdiction: If mediation fails, the dispute falls under the exclusive jurisdiction of the courts of Bordeaux, France.

Consumer protection rules from the User's country of residence remain applicable where mandatory under Article 6(2) of EU Regulation No. 593/2008 (Rome I).

• Severability: If any provision of these Terms is held invalid, illegal or unenforceable, the remaining provisions shall continue in full force and effect.
• No waiver: The failure of the Company to enforce any right or provision of these Terms shall not constitute a waiver of such right or provision.
• Entire agreement: These Terms, together with the Privacy Policy, constitute the entire agreement between the User and the Company regarding the use of the Service and supersede all prior agreements, representations and understandings.
• Assignment: The Company may assign its rights and obligations under these Terms to a third party (e.g., in connection with a merger, acquisition or sale of assets) without the User's prior consent, provided the assignee agrees to be bound by these Terms. The User may not assign their rights without the Company's written consent.
• Language: These Terms are available in English, French, Spanish, German, Portuguese, Italian, Turkish, Russian, Indonesian, Japanese, and Arabic. In case of discrepancy, the French version prevails.
