xPrufy - Terms of Use
Version 16.0 — Last Updated: July 6, 2026
By downloading, installing, or using xPrufy ("the App"), you agree to be bound by these Terms of Use. If you do not agree to these Terms, do not use the App.
You must be at least 18 years old to use this App. By using the App, you represent and warrant that you are 18 or older.
xPrufy is a capture and chain-of-custody tool with cryptographic integrity aids: photos, videos, and audio recordings can be sealed with hashes and metadata signatures (including RSA), GPS metadata, optional RFC 3161 timestamps when you are online and those materials are obtained, and optional Bitcoin blockchain timestamping via OpenTimestamps for evidence fingerprints (status on each record shows pending vs confirmed). It is not a substitute for independent professional review where your situation requires it. You can browse and select records in All Files; each record includes a reliability score summarizing which checks were recorded.
By default, new installations use "Standard" signing: an RSA key pair is created on the device for signing record metadata. Optional modes include "Professional" (adds a device identity certificate in metadata) and "Device-Bound" on Android (private signing identity in Keystore / hardware security features when available). You may export or restore the RSA signing identity when the selected mode allows it; Device-Bound identities are not exportable by design.
The App currently provides core functionality without mandatory paid tiers. If paid features, subscriptions, or one-time purchases are introduced in future versions, those offers will be clearly labeled in-app before purchase.
The App provides tools for evidence integrity verification. It does NOT provide legal advice, guarantee any outcome in a dispute or proceeding, or ensure compliance with local recording laws.
You may use this App ONLY for lawful purposes, including:
Lawful evidence collection by authorized professionals
Documentation for investigations, incident records, and formal reports
Workplace safety documentation and compliance
Insurance claims and professional investigations
Personal documentation with appropriate consent
Accident and incident documentation
Property inspections and assessments
You may NOT use this App to:
Record individuals without consent where prohibited by law
Violate federal, state, or local wiretapping statutes
Engage in illegal surveillance, stalking, or harassment
Record in prohibited locations (for example voting booths or medical facilities)
Violate privacy rights or reasonable expectations of privacy
Tamper with, alter, or fabricate evidence records
Violate any applicable recording consent laws in your jurisdiction
Infringe on intellectual property or confidential information
Record minors without parental consent where required
Use the App in any manner that violates local, state, federal, or international law
Recording consent laws vary by jurisdiction. Some jurisdictions require all parties to consent to recording (two-party consent), while others require only one party to consent (one-party consent).
YOU are solely responsible for:
Understanding and complying with recording laws in your jurisdiction
Obtaining required consents before recording
Providing notice when required by law
Ensuring your use of the App is lawful
We provide NO legal advice regarding recording consent laws. Consult a qualified attorney in your jurisdiction if you have questions.
You agree that YOU are responsible for:
All content you capture, create, or store using the App
Maintaining the security of your device and screen lock
Choosing an appropriate evidence-signing mode and understanding that changing mode creates a new signing identity for future captures
Backup and preservation of evidence data, Recovery Keys, and any RSA signing-identity backups — the App provides tools such as Settings → Back Up Files (writes an EvidenceBackup_….zip that includes media, metadata, and your HMAC Recovery Key; not password-protected by the App), Export with Proof (from All Files or a record's detail ⋮ menu), Advanced exports, and RSA signing-identity exports (when your mode allows it); the HMAC Recovery Key is included only inside full EvidenceBackup ZIPs from Back Up Files, not as a separate export; you must use them appropriately and protect any files you save or send
Optional features such as strict capture mode and exports — including ensuring each use is lawful where you are
Compliance with chain-of-custody or documentation procedures in your jurisdiction
Appropriate use of exported records in your own workflow
Any legal consequences arising from your recordings or use of the App
Maintaining control of exported evidence packages, audit-trail JSON (active evidence and recycle bin only — not a history of items permanently removed from the bin), and backups
THIS APP DOES NOT PROVIDE LEGAL ADVICE.
Nothing in the App, these Terms, the Privacy Policy, or support communications constitutes legal advice. The App provides technical tools only.
Consult a qualified attorney regarding:
How evidence should be handled in your case
Recording consent requirements in your jurisdiction
Proper chain-of-custody procedures
Data retention and privacy obligations
THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTY OF ANY KIND.
WE EXPRESSLY DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING BUT NOT LIMITED TO:
Warranties of merchantability, fitness for a particular purpose, and non-infringement
Warranties that the App will be uninterrupted, error-free, or secure
Warranties regarding the accuracy, reliability, or completeness of content
Warranties about how exported records will be treated by third parties
Warranties regarding blockchain confirmation times or timestamp availability
NO ORAL OR WRITTEN INFORMATION OR ADVICE GIVEN BY US OR OUR REPRESENTATIVES SHALL CREATE A WARRANTY.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE SHALL NOT BE LIABLE FOR:
Evidence being rejected or disputed by third parties
Technical failures during evidence capture or storage
Loss of evidence data due to device failure, loss, or theft
Blockchain network delays or failures
Timestamp authority unavailability
GPS inaccuracies or location service failures
Legal consequences arising from improper use of the App
Privacy violations or illegal recording by users
Data breaches resulting from lost or stolen devices
IN NO EVENT SHALL OUR TOTAL LIABILITY EXCEED THE AMOUNT YOU PAID FOR THE APP (IF ANY) IN THE 12 MONTHS PRECEDING THE CLAIM.
You agree to indemnify, defend, and hold harmless the App developers, publishers, and affiliates from any claims, damages, losses, liabilities, and expenses (including reasonable attorney fees) arising from:
Your use or misuse of the App
Your violation of these Terms
Your violation of any laws, including recording consent laws
Your violation of any third-party rights, including privacy or intellectual property
Any content you capture, create, or share using the App
Unauthorized recording or surveillance
Your use of the App is also governed by our Privacy Policy, which is incorporated into these Terms by reference.
Key points:
Evidence files and metadata are stored locally on your device by default
There is no vendor cloud account — you control exports and backups
For timestamping, only cryptographic hashes are sent to third-party time services (see the Privacy Policy for hostnames); media and GPS are not sent to those services for anchoring
We do not access, view, or host your evidence data on our servers
If you export, share, or back up data, you choose what leaves the device — for example Back Up Files (ZIP), Export with Proof (All Files or record detail menu), plain-file share, or Advanced exports; standard backups and plain shares are not encrypted by the App unless you use separate tools; optional RSA signing material may be inside a full EvidenceBackup ZIP (readable like the Recovery Key inside that archive) or in a separate Advanced RSA export (plaintext JSON)
See Settings → Privacy Policy in the app for full details.
The App and all content, features, and functionality are owned by us and are protected by copyright, trademark, and other intellectual property laws.
You may not:
Copy, modify, or reverse-engineer the App
Remove or alter proprietary notices
Use the App to develop competing products
You retain all rights to evidence content you create.
We reserve the right to terminate or suspend your access to the App at any time, with or without notice, for:
Violation of these Terms
Illegal use of the App
Activities that harm other users or third parties
You may terminate your use at any time by uninstalling the App. Upon termination, all data remains on your device until you delete it.
We may update these Terms from time to time. Material changes will:
Increment the in-app Terms version number (see the first-run summary and this screen)
Require re-acceptance on next App launch
Be effective upon your acceptance
Continued use after changes constitutes acceptance of new Terms. Check the version number and date at the top periodically.
If future versions include paid features, subscriptions, or one-time purchases, additional billing terms will apply and will be shown before purchase. Those terms may include pricing, billing cadence, renewal/cancellation rules, refund handling under applicable store policies, and taxes where required. Any such changes will be reflected in these Terms and, where required, presented for re-acceptance.
These Terms shall be governed by and construed in accordance with the laws of the jurisdiction where the App developer is located, without regard to conflict of law principles.
Any disputes arising from these Terms or use of the App shall be subject to the exclusive jurisdiction of the courts in that location.
If any provision of these Terms is found to be unenforceable or invalid, that provision shall be limited or eliminated to the minimum extent necessary so that these Terms remain in full force and effect.
These Terms, together with the Privacy Policy, constitute the entire agreement between you and us regarding the App and supersede all prior agreements and understandings.
For questions about these Terms, contact us through the support channel listed in the App Store or Google Play Store.
BY USING XPRUFY, YOU ACKNOWLEDGE THAT YOU HAVE READ, UNDERSTOOD, AND AGREE TO BE BOUND BY THESE TERMS OF USE.
