Terms of use
Last updated: 6 September 2026
1. About these terms
These terms are between you and Peth Pty Ltd (ACN 652 727 136), an Australian company (“we”, “us” or “our”). They cover the www.filesniff.dev website, free browser-based file checker, and associated File Sniff services (“Services”). References to the “apps” mean File Sniff for Mac, iPhone and iPad.
Please read these terms before using the Services. By using the Services, you agree to these terms to the extent they form an enforceable agreement under applicable law. If you use the Services on behalf of an organisation, you must have authority to do so. If you do not agree, do not use the Services.
Our privacy policy explains information handling. It is a notice about our practices, not a request for blanket consent to unrelated processing.
2. App Store licences and purchases
Apps obtained through the App Store are licensed, not sold. Their licence is governed by the licence agreement presented with the app in the App Store. Unless a separate custom licence is supplied there, Apple’s Standard Licensed Application End User Licence Agreement applies. These website terms are not a replacement custom App Store EULA.
Apple’s applicable usage rules determine permitted devices, account use and any eligible sharing. These terms do not impose a separate one-device restriction or remove sharing rights granted by the applicable licence.
The online checker is currently free. Native-app availability, prices and any purchase conditions will be shown in the relevant App Store listing or purchase screen. A “Coming soon” notice does not offer an app for immediate download or promise a release date. No subscription, free trial or lifetime-access arrangement is created by these terms alone.
Apple handles purchases and its refund-request process. Any statutory rights to a remedy remain available regardless of a store’s process or policy.
3. Permitted use
You may use the website and online checker for lawful personal or business purposes, including inspecting files you are authorised to access. We grant a limited, non-exclusive permission to use the website and its browser code as needed for that purpose, subject to these terms. The native apps remain subject to their applicable licence.
You must not interfere with the operation or security of the Services, attempt unauthorised access, infringe another person’s rights, or redistribute or sell our software or branding without permission. Restrictions do not apply to activities that applicable law or a relevant open-source licence expressly permits. Using File Sniff to inspect a suspicious file is not, by itself, prohibited use.
You may keep and use the results you generate and share them where you are authorised to do so. You remain responsible for checking whether results contain confidential filenames, paths or metadata before sharing them.
4. What File Sniff can and cannot establish
File Sniff identifies formats and related information from file contents. Detection depends on supported formats, the bytes available and the features of the version you use. The browser checker has narrower coverage and inspection limits than the native apps.
A format result or matching extension does not establish that a file is safe, authentic, complete or suitable for a particular purpose. Signatures and metadata can be forged. File Sniff is not an antivirus service, a guarantee of file integrity, or a repair tool. A result of “Unknown” means that the available analysis did not confidently identify a supported format.
Embedded Content Credentials and AI-origin declarations, where the native app reads them, are metadata reports. Their presence or absence does not by itself establish whether content was created by AI or whether it is trustworthy.
Consider results alongside the file’s source and any appropriate independent checks. Do not rely on File Sniff alone for security or other critical decisions.
5. Your files and actions you choose
Local analysis is read-only and does not upload files for identification. Some separate app actions write data: for example, confirmed extension changes, message conversion and exports. Renaming an extension does not convert or repair the file’s contents. Keep suitable backups before making changes to important files, and review prompts and output destinations.
You retain your rights in your files and data. Selecting a file for local analysis does not transfer ownership to us or grant us permission to publish it. You must have the rights or authority needed for any file you access, modify or share.
6. External services
The Services may link to external sites or open them at your request. Their availability, content and data handling are governed by their own terms and policies.
On Mac, an optional VirusTotal lookup opens a browser URL containing the file’s SHA-256 hash. The separate upload action opens VirusTotal’s upload page; it does not automatically submit the file. If you then upload it, VirusTotal receives and handles the contents. Do not submit confidential files or another person’s information without appropriate authority. See the privacy policy’s external-services section.
External reports are not File Sniff guarantees. Nothing in these terms excludes responsibility that we cannot lawfully exclude.
7. Intellectual property
Peth Pty Ltd and its licensors retain their rights in the File Sniff software, website, artwork, branding and documentation. Rights in third-party components remain with their respective owners and are subject to their applicable licences. Apple and other third-party names and marks belong to their respective owners.
No ownership rights in our intellectual property are transferred by using the Services. This does not limit your rights in your own files or the use of your inspection results described above.
8. Consumer rights and service limitations
Nothing in these terms excludes, restricts or modifies rights or remedies that cannot lawfully be excluded, including applicable guarantees under the Australian Consumer Law and mandatory consumer protections in other jurisdictions.
Subject to those rights, we do not promise that the Services will be uninterrupted, error-free, compatible with every device or file, or capable of identifying every format. We may correct errors and update features. Product descriptions and any express commitments we make continue to apply according to law.
If a product or service fails to meet an applicable consumer guarantee, you may be entitled to a remedy under law. These terms do not replace those remedies with a blanket “no refunds” rule or a fee-only liability cap.
9. Liability
To the extent permitted by applicable law, we exclude liability for indirect or consequential losses arising from use of the Services, such as lost profits or business interruption. This exclusion does not apply where it would be unlawful, does not limit statutory remedies, and does not exclude liability for fraud or deliberate misconduct.
We do not require you to indemnify us for every consequence of ordinary use. Each party remains responsible for its own conduct to the extent provided by applicable law. The native app’s applicable licence may contain additional provisions, subject to mandatory rights.
10. Changes, availability and ending use
You may stop using the website or checker at any time. We may update these terms prospectively and will show the revised date on this page. We will provide notice of material changes where required. Changes do not retrospectively remove accrued rights or override an existing purchase agreement without a lawful basis.
We may maintain, change or discontinue free website features. Where practicable, we will give reasonable notice of material changes. We may restrict access to protect the Services from abuse or address a material breach. If reasonable and practicable, we will give notice and an opportunity to address a breach before restriction; urgent security issues may require immediate action. This does not remove rights arising from a paid app licence or mandatory consumer law.
11. General provisions
If part of these terms is unenforceable, the remaining provisions continue to apply to the extent permitted by law. A delay in enforcing a right does not, by itself, waive that right.
These terms are governed by Queensland law, Australia, subject to mandatory laws and jurisdiction rights that protect consumers in their place of residence. They do not require you to give up access to a court or regulator where the law entitles you to use it.
