Terms of Service

Effective Date: 6 November 2026

These Terms of Service ("Terms") govern your download, installation, and use of the Tachyon Receipt mobile application ("Tachyon Receipt" or the "App"), provided by Tachyon Bit Limited ("Tachyon Bit", "we", "us", or "our"). By using the App, you agree to these Terms. If you do not agree, do not use the App.

1. The App

Tachyon Receipt is a personal receipt archive. It lets you manually record and organise receipts, search them, view optional photo or PDF attachments, manage a local Trash, and export selected records to an Excel workbook and ZIP package.

The Android release is offered as a one-time paid download through Google Play. The price shown at purchase may vary by country or region and may change over time. The App has no trial period, subscription, in-app purchase, or additional paid feature. Google Play processes the app purchase. Purchase and refund requests are subject to the applicable Google Play processes and policies and to consumer rights that cannot lawfully be excluded. The App does not provide OCR, tax or accounting advice, an online account, cloud synchronisation, or an App-operated cloud backup or restore service. Receipt data is stored in App storage on your device, subject to operating-system and device backup behavior described in the Privacy Policy.

2. Eligibility

You must use the App in accordance with applicable laws and these Terms. If you are not legally able to agree to these Terms on your own, you may use the App only with the permission and supervision of a parent or legal guardian who agrees to these Terms on your behalf.

3. Licence

Subject to these Terms, Tachyon Bit grants you a limited, personal, non-exclusive, non-transferable, and revocable licence to install and use the App for its intended purpose. No ownership of the App or its intellectual property is transferred to you.

Except where applicable law permits, you must not:

  • copy, modify, distribute, sell, lease, sublicense, or commercially exploit the App;
  • reverse engineer, decompile, or disassemble the App, or attempt to derive its source code;
  • bypass or interfere with the App's security or technical restrictions; or
  • use the App unlawfully or in a way that infringes another person's rights.

4. Your Receipt Information

You retain your rights in receipt information, descriptions, and attachments that you enter or select. You are responsible for ensuring that you have the right to store and use the information and files you add, including information about other people.

You are responsible for checking the accuracy and completeness of information you enter, including purchase dates, currencies, quantities, prices, tax, and totals. The App's calculations are provided as a convenience. GST-inclusive defaults or other calculated values may not reflect the tax treatment of a particular purchase, and you can edit supported amounts. Tachyon Receipt provides tools for personal receipt archiving. It does not provide professional accounting, tax, or legal advice, or certify or guarantee compliance with particular accounting, tax, or statutory record-retention requirements. You remain responsible for checking which requirements apply to your records and keeping any originals or other evidence required.

5. Attachments, Storage, and Export

You may add one supported image or PDF attachment to a receipt for viewing. Attachments are copied into App storage and may retain embedded metadata as described in the Privacy Policy. The App does not perform OCR or guarantee that every file can be opened on every device.

Receipt data and attachment copies are stored on your device. The App's Trash retains deleted receipts until you restore them or permanently delete them. The App does not provide its own cloud backup, synchronisation, or backup restoration. System-level backup or migration by Android, Apple, or another provider may operate according to your device settings and that provider's policies. Uninstalling the App or clearing its data may remove information stored only in the App. You are responsible for exporting or otherwise preserving records you need.

Permanently deleting a receipt does not erase its information from previously created exports, recipient copies, or system backups. Export cleanup is a separate action. Temporary export files and retained sharing ZIP copies follow the automatic and user-initiated cleanup rules described in Section 3 of the Privacy Policy; permanently deleting a receipt does not separately remove that information from these copies.

You may export selected receipt data as an Excel workbook and ZIP package to a folder you choose. You are responsible for protecting exported files and checking their contents. If you share them with another app, service, or person, that recipient may retain or further share them under its own terms.

More > Clear exported files lets you select all or individual listed exports and confirm deletion. The list covers only exports recorded locally from the introduction of this feature onward; the feature does not scan for earlier or otherwise unregistered exports. For each selected export, the App attempts to delete the recorded export folder and all its contents, the accompanying ZIP file, and any recorded sharing ZIP copy retained in the App's cache. Keep any files you wish to preserve outside the selected export folders before confirming. Deleted export files do not enter the App's receipt Trash, and the App provides no undo or restoration of them.

Export cleanup does not delete receipt records, folders, tags, or receipt attachments stored in the App, or original source files kept outside the selected export folders. It does not recall copies already shared or remove separately saved copies or system backups. Removal depends on access to the recorded locations and the storage provider, and may fail or complete only in part. The App reports cleanup results and retains failed entries for you to retry. Moved, renamed, unregistered, or otherwise remaining files may need to be managed through your file manager or storage provider, as described in Section 3 of the Privacy Policy.

6. Privacy

The App's handling of information is described in the Tachyon Receipt Privacy Policy. Receipt information is processed on your device and is not sent to a Tachyon Bit receipt-content server by the App. When you contact Tachyon Bit or choose to share information with another app, the Privacy Policy and the recipient's own terms explain the applicable handling.

7. Acceptable Use

You must not use the App to store or distribute unlawful material, infringe another person's privacy or intellectual-property rights, interfere with the App or another person's device, or attempt to access data you are not authorised to use. You are responsible for your device security and for keeping any exports in a location you consider appropriate.

8. Third-Party Services

PDFs are parsed and displayed locally by a component included in the App. Viewing a PDF does not require sending it to an external viewing service. The App also uses operating-system interfaces for camera capture, photo and file selection, export storage and deletion, and sharing. Access to an export destination and the handling of files there depend on the permissions you grant and the selected storage provider. System backup or migration, where available, is provided by the device or platform provider.

Third-party services, including Google Play, Apple platform services, and receiving apps or storage services supplied by other providers, are governed by those providers' terms and privacy policies. Those providers operate their own services. This description does not exclude our responsibilities for the App and the components we integrate, including their handling of data as described in the Privacy Policy.

9. Updates and Availability

We may update the App to fix issues, improve security, or maintain compatibility. Features may change or become unavailable. We do not guarantee uninterrupted or error-free operation, or that the App will work with every device or file. We may suspend or discontinue the App where reasonably necessary for legal, security, technical, or business reasons, subject to rights that cannot lawfully be limited.

10. Intellectual Property

The App, including its software, design, branding, and documentation, is owned by or licensed to Tachyon Bit Limited and protected by applicable intellectual-property laws. You may not use Tachyon Bit's name, marks, or logos without permission, except as permitted by law.

11. Disclaimers and Liability

The App is provided on an "as available" basis. To the maximum extent permitted by law, we do not guarantee that the App will be uninterrupted, error-free, or suitable for a particular purpose. You should keep independent copies of important records and verify exported data before relying on it.

Nothing in these Terms excludes, restricts, or modifies a consumer guarantee, right, or remedy that cannot lawfully be excluded or limited. This includes rights available to consumers under the New Zealand Consumer Guarantees Act 1993 and the Australian Consumer Law, where applicable.

To the extent permitted by law, Tachyon Bit is not liable for indirect or consequential loss arising from use of the App, including loss caused by a device failure, operating-system backup or restore, user-selected deletion, or a third-party sharing or storage service. This does not limit liability that cannot lawfully be excluded or limited.

12. Suspension and Termination

You may stop using the App at any time. You may delete receipt records, clean up listed exports within the App, and uninstall it. Uninstalling or clearing App data may remove receipt data and export cleanup records without deleting exported files outside App storage. Preserve information you need and, if you want to remove listed exports, use Clear exported files before uninstalling or clearing App data. Files that remain must be managed separately through your file manager or storage provider. We may suspend or end your permission to use the App if you materially breach these Terms or use the App unlawfully. Terms that by their nature should continue after termination will remain in effect.

13. Changes to These Terms

We may update these Terms to reflect changes to the App or applicable requirements. The effective date above identifies the current version. If renewed consent is required, the App will display the updated Terms and ask you to accept them before continued use. Changes do not remove rights that cannot lawfully be limited.

14. Governing Law

These Terms are governed by the laws of New Zealand, without limiting any mandatory consumer protections that apply where you live. New Zealand courts have non-exclusive jurisdiction over disputes relating to these Terms. Australian consumers retain rights under the Australian Consumer Law and other mandatory laws applicable in their state or territory.
