Last updated: October 22, 2026
1. Acceptance of Terms
By downloading, installing, accessing, or using Vaultar ("the Application"), you acknowledge that you have read, understood, and agree to be bound by these Terms of Use ("Terms") and our Privacy Policy. If you do not agree to these Terms, you must not install or use the Application.
These Terms apply to all users of the Application, including users who access the Application through Google Play or other authorized distribution channels. Your continued use of the Application following any modification to these Terms constitutes acceptance of such modifications.
2. License Grant
Subject to your compliance with these Terms, MJrFusion grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use the Application on Android devices that you own or control, solely for your personal or internal business purposes.
- You may not:
- (a)copy, modify, distribute, sell, or lease any part of the Application;
- (b)reverse engineer, decompile, or disassemble the Application, except to the extent permitted by applicable law;
- (c)remove any proprietary notices from the Application;
- (d)use the Application for any illegal or unauthorized purpose; or
- (e)make the Application available over a network where it could be used by multiple devices simultaneously.
All rights not expressly granted herein are reserved by MJrFusion. The Application is licensed, not sold. This license does not grant you any ownership interest in the Application or its intellectual property.
3. Acceptable Use
- You agree to use the Application only for lawful purposes and in accordance with these Terms. You shall not:
- (a)use the Application to store, process, or transmit any content that is illegal, infringing, defamatory, obscene, or otherwise objectionable;
- (b)interfere with or disrupt the integrity or performance of the Application;
- (c)attempt to gain unauthorized access to any systems or networks connected to the Application;
- (d)use the Application to violate any applicable local, state, national, or international law or regulation; or
- (e)encourage or facilitate any third party to do any of the foregoing.
MJrFusion reserves the right to investigate and take appropriate legal action against anyone who violates this section, including terminating your license, reporting you to law enforcement, and seeking damages.
4. Your Content & Intellectual Property
You retain all right, title, and interest in and to the documents, files, and data ("User Content") that you create, scan, import, or store using the Application. MJrFusion claims no ownership rights over your User Content.
By using the Application, you grant MJrFusion a limited, worldwide, royalty-free license to process your User Content solely to the extent necessary to provide the Application's functionality (e.g., rendering documents, generating thumbnails, performing on-device OCR). This license is limited to on-device processing and does not permit MJrFusion to access, view, or transmit your User Content off your device.
You represent and warrant that you have all necessary rights to your User Content and that your User Content and its processing through the Application do not violate these Terms or any applicable law or third-party rights.
5. Premium Features & In-App Purchases
The Application offers optional Premium features (including on-device OCR text recognition and an ad-free experience) available as a one-time purchase through Google Play's billing system ("In-App Purchase").
All In-App Purchases are processed by Google Play and are subject to the Google Play Terms of Service and Google Payments Terms of Service. MJrFusion is not a party to the payment transaction and does not receive or store your payment information.
Upon successful purchase, Premium features are associated with your Google account and may be restored on compatible devices where you are signed in with the same Google account. Premium features are licensed, not sold, and are subject to the same license restrictions as the Application.
Refunds for In-App Purchases are governed exclusively by Google Play's refund policy. MJrFusion does not process refunds directly. To request a refund, you must contact Google Play support.
MJrFusion reserves the right to modify, replace, or discontinue Premium features at any time, provided that such changes do not materially diminish the value of features you have already purchased.
6. Free Version & Advertising
The free version of the Application is supported by advertising delivered through Google AdMob and related Google advertising services. Advertisements may include interstitial ads, banner ads, or other formats.
Google's advertising services may use the Android Advertising ID (AAID) and other identifiers to deliver personalized ads, subject to your device settings and Google's privacy policies. MJrFusion does not control Google's advertising practices.
The Application does not use the content of your documents, files, or User Content for advertising targeting or profiling. Advertising is the sole monetization mechanism in the free version; no subscription or recurring charges apply.
You may upgrade to the Premium version at any time to remove advertisements. The Premium upgrade is a one-time purchase, not a subscription.
7. Privacy & Data Protection
Your privacy is important to us. The Application's data collection, use, and storage practices are described in our Privacy Policy, which is incorporated into these Terms by reference. By using the Application, you consent to the practices described in the Privacy Policy.
The Application is designed with a local-first architecture: your documents and data remain on your device unless you explicitly choose to share or export them. MJrFusion does not operate cloud storage for your documents and does not have access to your User Content.
The Application may transmit limited, non-personal data to third-party service providers for analytics (Firebase Analytics), crash reporting (Firebase Crashlytics), remote configuration (Firebase Remote Config), and advertising (Google AdMob), as described in the Privacy Policy.
8. Security
The Application offers optional security features including PIN protection and biometric authentication (fingerprint, face recognition) using Android's BiometricPrompt API. These features are provided as a convenience and do not guarantee absolute security.
Authentication credentials (PIN hashes, biometric keys) are stored locally on your device using Android's secure storage mechanisms (EncryptedSharedPreferences, Android Keystore). MJrFusion does not have access to these credentials.
You are responsible for maintaining the security of your device and your authentication credentials. MJrFusion is not liable for unauthorized access to your User Content resulting from device compromise, credential disclosure, or failure to use available security features.
9. Local-First Architecture
The Application operates entirely on your device ("local-first"). No user account or cloud synchronization is required or performed by the Application. Your documents, collections, metadata, and settings are stored in local storage on your device.
Documents never leave your device unless you explicitly initiate sharing, exporting, or sending through Android's system share sheet or file provider. MJrFusion does not operate servers for document storage, synchronization, or backup.
You maintain complete control over your data. Uninstalling the Application may result in the loss of locally stored data, depending on your device and Android version. MJrFusion recommends exporting important documents before uninstalling.
10. No Warranty
THE APPLICATION IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.

- (A)THE TOTAL AMOUNT YOU PAID FOR PREMIUM FEATURES IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM; OR
- (B)TEN UNITED STATES DOLLARS (USD $10.00).
SOME JURISDICTIONS DO NOT ALLOW THE LIMITATION OR EXCLUSION OF LIABILITY FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THE ABOVE LIMITATIONS MAY NOT APPLY TO YOU IN FULL.
12. Indemnification
- You agree to indemnify, defend, and hold harmless MJrFusion, its officers, directors, employees, and agents from and against any and all claims, damages, obligations, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising from or related to:

- (b)your User Content;
- (c)your violation of any third-party right, including intellectual property rights; or
- (d)your violation of any applicable law.
13. Termination
These Terms remain in effect until terminated by you or MJrFusion. You may terminate these Terms at any time by uninstalling the Application and ceasing all use. MJrFusion may terminate these Terms and your license immediately, without prior notice, if you breach any provision of these Terms.
- Upon termination:
- (a)your license to use the Application ends immediately;
- (b)you must cease all use of the Application and destroy all copies;
- (c)Sections 4, 7, 10, 11, 12, 13, 14, and 15 shall survive termination.
14. Changes to These Terms
MJrFusion may modify these Terms at any time. Updated versions will be posted within the Application and/or on the official Google Play Store listing, with the "Last updated" date revised accordingly.
If changes are material, MJrFusion will provide notice through the Application or other reasonable means. Your continued use of the Application after the effective date of any changes constitutes acceptance of the revised Terms. If you do not agree to the changes, you must stop using the Application.
15. Governing Law & Dispute Resolution
These Terms shall be governed by and construed in accordance with the laws of the jurisdiction where MJrFusion is established, without regard to conflict of law principles.
Any dispute arising out of or relating to these Terms or the Application shall be resolved through binding arbitration in accordance with the rules of the applicable arbitration body, except that either party may seek injunctive relief in any court of competent jurisdiction.
If arbitration is not available or enforceable for any reason, disputes shall be resolved in the courts of competent jurisdiction in the jurisdiction where MJrFusion is established.
16. General Provisions
These Terms, together with the Privacy Policy, constitute the entire agreement between you and MJrFusion regarding the Application. If any provision is found unenforceable, the remaining provisions shall continue in full force and effect.
No waiver of any right under these Terms shall be effective unless in writing. The failure to enforce any provision shall not constitute a waiver of that or any other provision.
You may not assign or transfer these Terms without MJrFusion's prior written consent. MJrFusion may assign its rights and obligations freely.
17. Contact Information
For questions, concerns, or notices regarding these Terms, you may contact MJrFusion through the official Google Play Store listing for Vaultar or via the contact channels listed on the official MJrFusion website.
Notices to MJrFusion should be sent to the address or email provided in the Application's Google Play Store listing or the official MJrFusion website.
