Terms of Service

1. Agreement to These Terms

These Terms of Service ("Terms") form a legally binding agreement between you ("you" or "User") and Yogendra Singh, an independent software developer based in Pune, Maharashtra, India, operating the TeraConvert product ("TeraConvert", "we", "us", or "our"). They govern your access to and use of:

- the TeraConvert website at teraconvert.com and all subdomains (the "Website"), - the free browser-based file converter served at teraconvert.com (the "Web App"), and - the paid TeraConvert desktop application for macOS (the "Desktop App").

The Website, the Web App, and the Desktop App are collectively referred to as the "Service". By accessing or using any part of the Service, you confirm that you have read, understood, and agreed to be bound by these Terms and by our Privacy Policy Privacy Policy, which is incorporated into these Terms by reference. If you do not agree, do not access or use the Service.

2. Who We Are

TeraConvert is operated by Yogendra Singh as a sole proprietor based in Pune, Maharashtra, India. For the purposes of India's Digital Personal Data Protection Act, 2023 (the "DPDP Act") and the EU/UK General Data Protection Regulation ("GDPR"), Yogendra Singh is the Data Fiduciary / Data Controller for personal data processed through the Service. Yogendra Singh is also the sole licensor of the Desktop App.

You can reach us at [email protected] for any question, request, or notice under these Terms.

3. Description of the Service

TeraConvert is a local-first file conversion product. The Service converts files between popular image, document, audio, video, archive, spreadsheet, and presentation formats. Both the Web App and the Desktop App are engineered so that every conversion runs entirely on your own device.

Web App. Conversions run inside your browser tab using standard browser APIs (Canvas, WebCodecs, WebAssembly, Web Workers, and the File System Access API where supported). The file bytes never reach our servers or any third-party server as part of the conversion process. The Web App is offered free of charge with optional rate-limiting and usage caps that we may apply at our discretion to keep the Service available for everyone.

Desktop App. Conversions run on your local operating system using Apple's built-in conversion tools on macOS (such as sips, textutil, and qlmanage) together with standard open-source command-line engines (including FFmpeg, ImageMagick, Pandoc, Ghostscript, Tesseract, LibreOffice, Calibre, and qpdf) that are installed on your machine through your operating system's package manager (Homebrew on macOS). The Desktop App orchestrates these tools locally. It does not embed any cloud conversion service.

The Desktop App requires an internet connection only (a) for one-time account sign-in and license activation, (b) to check for software updates, (c) for in-app links to documentation or support, and (d) to send crash reports if you opt into crash reporting. None of these exchanges include the contents of the files you convert.

We may, at our sole discretion, add, modify, suspend, or remove features of the Service at any time without notice, except where such changes materially reduce the functionality of a paid feature for which you have already paid.

4. Eligibility

The Service is intended for individuals who are at least 18 years of age or the age of majority in their jurisdiction, whichever is higher. By using the Service, you represent and warrant that you meet this age requirement and that you have the legal capacity to enter into these Terms. If you are using the Service on behalf of a company, organisation, or other legal entity, you represent that you have the authority to bind that entity to these Terms, and references to "you" include that entity.

The Service is not directed at children, and we do not knowingly collect personal data from children. See Section 12 of our Privacy Policy for details.

5. Accounts and Authentication

Some parts of the Service, including the dashboard, the Desktop App download, license management, and the Desktop App itself, require a TeraConvert account. Accounts are created and authenticated through our identity provider Clerk (Clerk Inc.), which acts as a processor on our behalf. By creating an account you agree to Clerk's role as described in our Privacy Policy.

You are responsible for:

- providing accurate and current information when registering, - keeping your account credentials confidential and not sharing your account with any other person, - all activity that occurs under your account, whether or not you authorised it, - notifying us promptly at [email protected] if you suspect any unauthorised access to your account.

We may suspend or terminate any account that we reasonably believe has been compromised, has been used to violate these Terms, or has been used to commit fraud or to abuse the Service.

6. License Grant (Desktop App)

Subject to your continued compliance with these Terms and payment of all applicable fees, we grant you a personal, limited, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use the Desktop App on devices that you personally own or control, for your own internal use, in object code form only.

One license per individual end user. A single TeraConvert desktop license is intended for one human user. You may install and activate the Desktop App on a reasonable number of personal devices that you yourself use (we currently set this limit at 3 activations per license; we may adjust the limit and will not reduce it in a way that materially affects your existing use). You can move your license between devices using the in-app deactivation flow or the customer portal.

You may not:

- copy, distribute, sell, sublicense, rent, lease, lend, or otherwise make the Desktop App available to any third party, - share your account or license entitlement with any other person or organisation, - reverse-engineer, decompile, disassemble, or attempt to derive the source code of the Desktop App, except to the extent such restriction is expressly prohibited by applicable law, - remove, alter, or obscure any copyright, trademark, or other proprietary notice in the Desktop App, - use the Desktop App to develop a competing product, or use it as a component in a service that you offer to third parties, - circumvent or attempt to circumvent the license activation, validation, or update mechanisms of the Desktop App.

The Desktop App is licensed, not sold. We retain all right, title, and interest in and to the Desktop App and all copies thereof. All rights not expressly granted to you are reserved by us.

7. Acceptable Use

You agree to use the Service only for lawful purposes and in a way that respects the rights of others and the integrity of the Service. You will not, and will not permit any third party to:

- use the Service to create, store, process, transmit, or distribute content that is illegal under any applicable law, that infringes any intellectual property or other right of any person, that is defamatory, harassing, hateful, or invasive of privacy, or that involves child sexual abuse material, terrorist content, or content prohibited by the Information Technology Act, 2000 and rules made thereunder, - use the Service in any way that could damage, disable, overburden, or impair the Service, or interfere with any other party's use of the Service, - use any robot, spider, scraper, or other automated means to access the Service for any purpose without our express written permission, except for well-behaved search-engine indexing in accordance with our robots.txt, - bypass, circumvent, or attempt to bypass any rate limit, usage cap, paywall, or access control, - introduce any virus, worm, trojan, ransomware, time bomb, or other malicious code into the Service, - attempt to gain unauthorised access to any account, server, or network connected to the Service.

You are solely responsible for the content of the files you convert through the Service and for ensuring that you have the necessary rights to do so.

8. Your Files and Your Content

You retain full ownership of, and all rights in, every file you process through the Service. We do not claim, and these Terms do not grant us, any licence over the contents of those files.

Because every conversion is performed on your device and the file bytes never reach our infrastructure, we have no copy of your files to lose, leak, or share. The privacy and integrity of the source content remain entirely in your hands, subject to the security of your own device and operating system.

9. Our Intellectual Property

The Service, including the TeraConvert name, the TeraConvert logo, the Website design, the Web App and Desktop App user interfaces, all copy, illustrations, brand assets, format catalogue, conversion routing logic, and proprietary code, are owned by Yogendra Singh and are protected by Indian and international copyright, trademark, and other intellectual property laws.

Nothing in these Terms transfers to you any right, title, or interest in or to any of the foregoing. You may not use any TeraConvert trademark or brand asset without our prior written consent, except for fair-use references that accurately describe the Service.

10. Open-Source and Third-Party Components

The Service depends on, and the Desktop App orchestrates, a number of independent open-source projects, including without limitation FFmpeg, ImageMagick, Pandoc, Ghostscript, Tesseract, LibreOffice, Calibre, and qpdf. Each of these projects is the property of its respective authors and is distributed under its own open-source licence (typically LGPL, GPL, MPL, BSD, MIT, or Apache 2.0). The Desktop App invokes these tools as separate processes installed on your machine; it does not statically link or redistribute them.

When you install any of these tools through your operating system's package manager, your use of those tools is governed by the licence terms set by their respective authors and not by these Terms. We make no warranty as to those tools and accept no liability for them.

A full attribution list, with links to each project and its licence, is available in the "About" screen of the Desktop App and at teraconvert.com/credits.

11. Payment, Pricing, and Taxes

The Web App is free. The Desktop App is sold as a one-time license. Prices for paid features are shown at the point of purchase and are denominated in the currency displayed at checkout. All payments are processed by our payments provider Polar.sh (Polar Software Inc.), which acts as the merchant of record where applicable. Polar collects your billing email, billing country, and payment instrument details through its PCI-DSS compliant payment processors. We never see or store your full payment card number.

Applicable taxes (including GST in India, VAT in the EU and UK, and other sales taxes where required) are calculated and collected by Polar at checkout based on the billing address you provide and the law applicable at the time of the transaction.

We may change our prices at any time. Price changes apply only to purchases made after the change takes effect and do not affect any license you have already purchased.

12. Refunds and Cancellation

14-day refund window. If you are a consumer purchasing the Desktop App, you may request a full refund within 14 days of the date of purchase, provided that you have not made substantial use of the license and that no clear pattern of abuse is present. Refunds are processed by Polar.sh back to the original payment method, normally within 5 to 10 business days of approval, subject to your bank's or card network's processing time.

How to request a refund. Email [email protected] from the email address associated with your purchase, with the subject line "Refund request" and your Polar order ID. We do not require you to justify the request within the 14-day window.

After the refund window. Outside the 14-day window, purchases are non-refundable except where a refund is required by mandatory consumer protection law (for example, where the Service is materially defective and we cannot resolve the defect within a reasonable period, or where you are entitled to a statutory cooling-off right that we cannot lawfully exclude).

Effect of refund. When a refund is issued, the corresponding entitlement is revoked and the Desktop App will return to its unlicensed state on the next entitlement check. You agree to stop using the Desktop App once a refund has been issued.

13. Software Updates

The Desktop App includes an automatic update mechanism. When the Desktop App starts and periodically thereafter, it contacts our update endpoint at teraconvert.com to check whether a newer version is available. The update endpoint validates your entitlement against our payments provider and, if you are entitled to updates, returns a signed update bundle.

Update bundles are cryptographically signed with an ed25519 key. The Desktop App verifies the signature before installing any update; tampered or unsigned updates are rejected.

Updates may add, modify, or remove features, fix defects, address security issues, and adjust supported formats. We recommend that you keep the Desktop App up to date. We may discontinue updates for a particular operating system or hardware platform where it is no longer commercially or technically reasonable to support it, on reasonable notice.

14. Privacy and Data Protection

Your use of the Service is also governed by our Privacy Policy Privacy Policy, which describes what personal data we collect, why we collect it, who processes it on our behalf, where it is stored, how long we keep it, and the rights you have over it. The Privacy Policy is incorporated into these Terms by reference. By using the Service you consent to our data practices as described in the Privacy Policy.

15. Disclaimer of Warranties

The Service is provided "AS IS" and "AS AVAILABLE", without warranty of any kind, whether express, implied, statutory, or otherwise. To the maximum extent permitted by applicable law, we disclaim all warranties, including implied warranties of merchantability, fitness for a particular purpose, title, non-infringement, accuracy, and any warranty arising from a course of dealing or usage of trade.

Without limiting the foregoing, we do not warrant that:

- the Service will be uninterrupted, timely, secure, or error-free, - the results obtained from the use of the Service will be accurate, reliable, or fit for any particular purpose, - the output of any conversion will be identical in fidelity, formatting, structure, metadata, colour, or quality to the source file, - the Service will be compatible with every device, operating system version, or third-party tool, - defects in the Service will be corrected.

You are responsible for verifying conversion output before relying on it for any important purpose, and for keeping backups of your original files.

16. Limitation of Liability

To the maximum extent permitted by applicable law:

(a) Exclusion of indirect damages. Neither party shall be liable to the other for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, business, goodwill, data, or anticipated savings, even if advised of the possibility of such damages and even if a limited remedy fails of its essential purpose.

(b) Aggregate cap. Our aggregate liability to you for all claims arising out of or relating to these Terms or the Service, whether in contract, tort (including negligence), strict liability, or otherwise, shall not exceed the greater of (i) the total amount you have paid to us for the Service in the twelve (12) months immediately preceding the event giving rise to the claim, or (ii) Indian Rupees ten thousand (INR 10,000).

(c) Carve-outs. Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, including liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that the law does not permit us to exclude or limit.

(d) Basis of the bargain. You acknowledge that the price of the Service reflects the allocation of risk set out in these Terms, that the limitations in this Section 16 are an essential element of the agreement between us, and that we would not have provided the Service to you on these terms without them.

17. Indemnification

You agree to indemnify, defend, and hold harmless Yogendra Singh and any of his affiliates, employees, agents, or contractors from and against any and all third-party claims, demands, losses, liabilities, damages, costs, and expenses (including reasonable legal fees) arising out of or related to (a) your use of the Service in breach of these Terms, (b) your violation of any law or any right of any third party, including any intellectual property or privacy right, in connection with your use of the Service, or (c) the content of the files you convert or otherwise process through the Service.

We will notify you promptly of any such claim, give you reasonable cooperation in defending it, and not settle it without your prior written consent, such consent not to be unreasonably withheld.

18. Termination

Termination by you. You may stop using the Service at any time. You may close your TeraConvert account by emailing [email protected] from the email address associated with your account.

Termination by us. We may suspend or terminate your access to all or part of the Service, with or without notice and at our reasonable discretion, if (a) you materially breach these Terms and (where the breach is curable) fail to cure the breach within 14 days of our written notice, (b) we are required to do so by applicable law or by an order of a competent authority, (c) we reasonably believe that your continued use of the Service poses a security, legal, or reputational risk to us or to other users, or (d) we discontinue the Service.

Effect of termination. Upon termination, your right to access and use the Service ceases. Sections 6 (License Grant), 8 (Your Files and Your Content), 9 (Our Intellectual Property), 11 (Payment), 15 (Disclaimer of Warranties), 16 (Limitation of Liability), 17 (Indemnification), 19 (Changes), 20 (Governing Law), 21 (Grievance Officer), and 22 (Miscellaneous), together with any other provision that by its nature should survive, will survive any termination of these Terms.

19. Changes to These Terms

We may update these Terms from time to time to reflect changes in the Service, our business, or applicable law. The "Last updated" date at the top of this page shows when the current version took effect.

For material changes that adversely affect your rights, we will notify you by email (where we have your address) or by a prominent notice on the Website at least 14 days before the change takes effect, where reasonably practicable. Your continued use of the Service after a change takes effect constitutes acceptance of the updated Terms. If you do not agree to the updated Terms, your sole remedy is to stop using the Service and, if applicable, to request a refund in accordance with Section 12.

20. Governing Law and Dispute Resolution

These Terms and any dispute or claim (including non-contractual disputes or claims) arising out of or in connection with them or their subject matter or formation are governed by and construed in accordance with the laws of India.

Good-faith negotiation. Before initiating any legal proceeding, the parties shall first attempt in good faith to resolve any dispute by written notice and discussion for a period of at least thirty (30) days from the date of the notice.

Jurisdiction. Subject to the good-faith negotiation requirement above, the courts of Pune, Maharashtra, India shall have exclusive jurisdiction over any dispute, controversy, or claim arising out of or in connection with these Terms or the Service, and you and we irrevocably submit to the exclusive jurisdiction of those courts.

Consumers in the EU, UK, and other protected jurisdictions. If you are a consumer resident in a jurisdiction whose mandatory consumer protection law gives you the right to bring proceedings in the courts of your country of residence and to rely on the protections of its law, nothing in this Section 20 deprives you of that right.

21. Grievance Officer (India)

Entire agreement. These Terms, together with the Privacy Policy and any additional terms presented to you at the point of purchase or activation, constitute the entire agreement between you and us regarding the Service and supersede any prior agreement on the same subject matter.

No waiver. Our failure to enforce any provision of these Terms is not a waiver of our right to enforce it later.

Severability. If any provision of these Terms is held to be invalid or unenforceable, that provision will be enforced to the maximum extent permitted and the remaining provisions will remain in full force and effect.

Assignment. You may not assign or transfer these Terms or any of your rights or obligations under them without our prior written consent.
