WellCalc Product Schedule · Android app

Product-specific Android schedule. This schedule supplements the separate Terms and Privacy Policy for package com.ryantinklepaugh.wellcalc.

Product purpose

WellCalc is a petroleum calculation and field-reference toolkit for traceable checks in field and office workflows. Calculations, reference material, saved work, and exports are tools for review, not a substitute for competent engineering judgment.

Core tools and WellCalc Pro

The core tier includes Well Control, Pipe & Annular, Pumps, Mud Engineering, and Unit Conversion calculations, and creation of one field job. WellCalc Pro unlocks the other calculation categories: Cementing, Directional, Production, Reservoir, Hydraulics, Drilling, Completions, Artificial Lift, Well Testing, Economics, and Casing Design. Pro also permits unlimited new field jobs and calculation-history CSV report export.

Saved records are not erased when Pro expires. Existing jobs remain readable and selectable; creating additional jobs and running Pro calculations requires current Pro access. Saved-data recovery export and the app’s legal, deletion, support, purchase-restoration, and subscription-management controls do not require Pro. A data-recovery archive is distinct from a Pro calculation report.

Data and export boundaries

Calculation inputs and results, saved jobs, favorites, notes, and history are stored on your device.
Core calculations do not require a WellCalc account.
Files are created when you direct an export or share action; your chosen destination and share service have their own behavior.
Historical calculation records that did not store a formula version or units cannot establish that provenance. Reports label those values Not recorded rather than inventing them.
Purchase and legal-choice evidence is processed separately from ordinary calculation records, as described in the Privacy Policy.

Reports are not engineering certificates. Independently confirm the meaning and units of every field before using a saved or exported result.

Required safety boundary

Results are informational engineering aids, not operating instructions. Review sources, assumptions, units, and limits, and independently verify every result before an operational, safety, regulatory, or financial decision.

Legal choices and verification

A decline or withdrawal takes effect locally at once and remains limited without recurring prompts. A current affirmative choice permits ordinary app access after it is durably stored on the device; signed-receipt delivery may retry in the background. Initiating a new subscription purchase additionally requires the current agreement’s server-signed receipt to be verified. Restoration and subscription management do not require a new affirmative choice and remain available in Limited Mode when the purchase service is configured.

Android proof is recorded separately from iOS proof. A service outage does not silently convert a decline into acceptance or relabel an iOS receipt as Android. Declining or withdrawing legal consent does not cancel an existing subscription or erase saved records.

Google Play subscriptions

WellCalc Pro is offered through monthly and annual Google Play subscriptions. The app shows the available plan’s localized recurring price and billing period; Google Play confirms the payment and any eligible introductory offer before purchase. Plans renew automatically unless you cancel renewal through Google Play, subject to the store’s terms and applicable law. Uninstalling WellCalc or withdrawing legal consent does not cancel renewal.

Use Google Play subscription management or the app’s Manage subscription control to manage or cancel renewal. Restore purchases checks genuine Google Play purchase access through RevenueCat; it does not start another purchase. Restoration depends on the store account and purchase being eligible. A cancelled renewal normally leaves access for the paid period unless a refund, revocation, expiration or other store action changes the entitlement.

The app’s purchase-restoration and subscription-management controls remain available even if you decline or withdraw legal consent. Missing billing configuration or a failed network request does not create Pro access, erase existing records, or prove that an existing entitlement has been revoked. Offline access relies on the purchase service’s previously cached entitlement evidence and applicable store status; it is not a promise of indefinite paid access without validation. Request purchase help through WellCalc support. Refund requests follow Google Play’s rules and applicable law.

Availability

The Google Play listing states current availability, supported devices, and the app version offered for download. This schedule does not promise a future release, a feature not present in the offered Android version, Android/iOS record synchronization, or transfer of purchases between stores.
