Conduit Bend by PierDo · Effective October 2026 · Version 1.0.0
Android package com.pierdo.conduitbend

Your bend sheets

Bend sheets, settings and your last calculator entries are stored on your device, in the app’s local storage and IndexedDB. Your theme choice and small counters that space out upgrade offers and the rating request are stored there too. The app does not upload any of it or provide cloud sync. There is no app account, no ads, no analytics SDK and no server of ours. We do not receive your sheets, measurements or anything else you enter.

Optional purchases

The only network use is Google Play and RevenueCat, to show the Pro price, buy Pro and restore a purchase. Nothing is sent until you open Conduit Bend Pro in the More tab, use one of its purchase buttons, Restore purchase or Check purchase status, or an upgrade offer opens: an offer asks Google Play and RevenueCat for the price when it opens. Your bend sheets and measurements are not sent to them.

Those services process purchase history and status, transaction identifiers, an app-specific anonymous customer identifier, locale and currency, and technical request information such as platform, app version and IP address. The price request names the screen that showed the offer, so a sale can be credited to it. Google Play handles payment details; the app does not receive payment-card numbers.

Pro is a permanent purchase, not a subscription. The app keeps your purchase status on the device so Pro works offline, and keeps pending-payment information to avoid repeating an uncertain checkout. Purchase-related data supports app functionality, purchase analytics, transaction handling and fraud prevention. We do not sell it or use it for advertising. See Google’s privacy policy and RevenueCat’s privacy policy.

Backups and files you choose

Backups (JSON) and text exports of a bend sheet are written only to a file you choose, in the place you choose. While the file is being written, the app makes a temporary copy in its private cache and removes it afterwards. A backup holds your settings and saved bend sheets, including the sheet you are editing, and never your purchase status. Keep backups private if your sheets carry job names or other personal notes. A destination service handles your exported file under its own terms. The app does not automatically upload exports.

Clearing the app’s data or uninstalling removes the sheets on this device. It does not remove files you exported, so keep a backup first if you may need your sheets. Removing local data does not refund purchases or erase Google Play or RevenueCat transaction records. Those services may retain records needed for restores, refunds, fraud prevention or legal obligations.

Rating prompt

Conduit Bend may occasionally ask for a rating with Google’s in-app review dialog. Google decides whether it appears. The app reads nothing from it: it cannot see whether you rated or what you wrote.

More from PierDo

The More from PierDo row only opens pierdo.net in your browser when you tap it. The app sends nothing with it.

Purchase-related data requests

Email pierdo.dev@gmail.com, name Conduit Bend and describe your request. We may need enough purchase information to find the record and verify the request. Never send passwords or payment-card details. Records needed for transaction, restore or legal obligations may be retained for those purposes. Remove local bend sheets on your device as described above.

A calculation aid

Conduit Bend is a calculation aid. Verify every mark against local code and your bender manufacturer’s marks, and try it on a scrap piece before you bend a stick.
