Snubline Support
Snubline provides educational rigging equations, assumed-input comparisons, log-weight examples and local scenario records. No independent professional validation or complete rope calibration dataset is available.
Records, sharing, and deletion
There is no account, app-operated cloud sync, or server copy of your jobs. Delete a job or gear item through its in-app controls after reviewing the confirmation. Deletion is permanent within the app; there is no Recently Deleted area. Snubline offers per-job educational comparison PDFs and scenario share cards, rather than a restorable bulk export. Keep useful copies before deleting records or replacing a device. Ordinary device backups depend on your Apple settings.
Pro access
The current Free tier includes the core calculator, model explanations, log estimator, up to three gear items, and one job. Pro adds expanded record creation, scenario comparison, educational comparison PDFs, share cards, custom rope profiles, and widgets. The updated Pro page offers annual and one-time Lifetime purchases at Apple’s displayed price. Historical monthly access remains supported while active; older installed versions may show earlier offers. Use Restore Purchases in the app to check eligible access. Restoring a purchase does not restore jobs.

Email captainlongevity@gmail.com with your app and iOS versions and a brief description. Remove client names, site details, and private information from screenshots. Records are not attached automatically. Manage subscriptions in iOS Settings > your name > Subscriptions; removing Snubline does not cancel billing.
