Customer care
For assistance, feature questions, accessibility concerns, purchase issues, or privacy requests, email admin@langsyslab.com.
To help us respond efficiently, include the product name, app version, device model, operating-system version, and a clear description of the issue. Screenshots are helpful, but please remove or obscure personal, financial, military, customer, contact, or other sensitive information unless it is necessary to resolve the request.
Purchases are processed by the applicable app marketplace, such as Apple’s App Store, Microsoft Store, or Google Play. Langsys LLC does not receive your complete card or bank details. Purchase availability, billing, refunds, family sharing, and restoration are governed by the marketplace and the product type shown before purchase.
If an eligible prior purchase is not recognized, first confirm that the device is signed in to the same marketplace account used for the original purchase, then use the app’s restore-purchases control when one is provided.

We do not sell personal information.
We do not use app information for third-party advertising or cross-app tracking.
MakerMerge and Military Net Pay are designed around local device storage. Data can leave a device when you choose to share, export, back up, contact support, or complete a marketplace purchase.
This policy applies to MakerMerge, Military Net Pay, and this website. A product may display additional disclosures for features unique to that app. If a specific disclosure conflicts with this general policy, the more specific disclosure controls for that feature.
MakerMerge may contain user-supplied templates, order records, text, image references, validation results, project history, and generated files. V1 keeps templates, projects, validation, and file generation local and does not use a Langsys cloud workspace.
In Military Net Pay, you may enter settings and informational pay-planning inputs such as rank, years of service, duty location, allowances, deductions, and related calculation selections. This information is used to provide the estimates you request.
Langsys LLC does not operate a server that automatically receives information entered into these apps unless an app clearly discloses a network-based feature before you use it.
Langsys apps are not designed to sell personal information, build advertising profiles, or track users across other companies’ apps and websites. Unless a store listing or in-app notice states otherwise, the apps do not include third-party advertising or behavioral-analytics SDKs.
This website does not intentionally set advertising cookies or use a Langsys-operated analytics account. Our hosting and network providers may process basic request information, such as IP address, browser type, date and time, and security events, to deliver and protect the site under their own privacy terms.
You control locally stored app information. Where an app provides settings or saved-data deletion, you can remove that information inside the app. Deleting the app generally removes its locally stored data from that device. Copies may remain in device backups, exported files, shared destinations, printouts, or third-party services until you delete them there.
Support correspondence is retained only as reasonably needed to answer the request, maintain business records, prevent abuse, or meet legal obligations. To request deletion of support correspondence, email admin@langsyslab.com with enough information to identify the messages.
Locally stored app information is protected by the operating system’s application sandbox and the security controls you use on your device. We use reasonable administrative and technical measures for information under our control. No device, storage method, transmission, or online service can be guaranteed completely secure. Protect your device, backups, exported files, and marketplace account, especially when an app contains customer, financial, military, or other sensitive information.
Langsys apps are business, productivity, and informational tools and are not directed to children under 13. We do not knowingly collect personal information from children through the apps. If you believe a child has sent personal information to support, contact us so we can review and delete it where appropriate.
We may update this policy as products, platform requirements, or laws change. The current version and effective date will be posted on this page. Material changes may also be disclosed in the applicable app or store listing.
