TowerBuild is a clean, offline notebook for builders, contractors, and renovation crews — log heights, flag vertical deviations, and keep your site dimensions structured, right from the scaffold.
No messy submenus, no required accounts. Each task lives on its own interactive card, ready for fast manual entry under any site lighting.
Keep a clean history of your vertical dimensions. Enter blueprint specs alongside actual physical readings and let the card work out the height difference for you.
Document uneven surfaces during level checks. Tally surface imperfections per area with rapid, responsive tap counters and instant haptic feedback.
Never get tripped up by mismatched blueprints. Switch between meters, millimeters, and inches instantly on a single, integrated manual interface.
Group your logs by room, level, or construction zone. Swipe smoothly through independent project cards to stay organized across large property inspections.
A taste of how TowerBuild thinks. Punch in numbers and watch the cards compute — nothing leaves this page.
Built by people who've actually held a tape measure in the rain.
We're a small crew of builders, drafters, and software makers who got tired of wrestling with bulky blueprint suites just to jot down a single height reading on a windy scaffold. TowerBuild grew straight out of that frustration — a pocket-sized site notebook made by people who've actually held a tape measure in the rain.
Our mission is plain: give on-site professionals a fast, offline, genuinely clear place to record what they measure. No accounts, no subscriptions, no sync headaches — just disciplined cards that respect your time and the everyday chaos of a live job site.
With TowerBuild you log vertical dimensions and compare blueprint specs against real measurements, track surface imperfections with rapid tap counters, switch between meters, millimeters, and inches in a single tap, and group every reading by room, level, or zone. Every entry stays on your device, ready whenever you are.
One promise: your site data belongs to you, and only you.
TowerBuild: Construction Log is built around one promise: your site data belongs to you, and only you. This app is designed to work entirely on your device, without collecting, storing, or transmitting any personal information. This policy explains, in plain terms, exactly how that works.
We collect nothing. TowerBuild has no sign-up, no user accounts, and no login. We do not ask for your name, email address, phone number, or location, and we do not gather analytics, usage statistics, or device identifiers. The measurements you enter — height logs, blueprint specs, surface defect counts, unit conversions, and zone groupings — are created and kept by you, on your device alone.
Because we never collect your data, there is nothing for us to use, analyze, profile, or sell. Every calculation — height deviations, unit conversions, defect tallies — runs locally on your device. Your information is never sent to us or to anyone else, and it is never used for advertising or marketing of any kind.
All of your entries are stored locally within the app on your device. There is no cloud backup, no remote server, and no synchronization service involved. We do not maintain any database of TowerBuild users or their measurements, because none of that data ever leaves your hands.
TowerBuild contains no third-party analytics tools, no advertising networks, no trackers, and no embedded SDKs that harvest data. The app operates fully offline and does not connect to external laser measures, sensors, or any other hardware or online service.
Since your information never leaves your device, it is not exposed to the risks that come with transmitting data over networks or holding it on shared servers. The strongest protection for your data is that it simply isn't anywhere else. We recommend keeping your device secured with a passcode or biometric lock for added peace of mind.
TowerBuild does not collect personal information from anyone, including children under the age of 13. The app is COPPA-friendly by design: with no data collection of any kind, there is nothing to gather from users of any age.
You are in full control of everything you enter. You can edit or clear individual logs at any time, and removing all app data is as simple as deleting TowerBuild from your device. Because there are no accounts and no backups, uninstalling the app permanently removes the information stored within it.
If we ever update this policy, we will revise the Effective Date shown above and publish the new version within the app. Since our core principle — collecting no data — is unlikely to change, any updates will typically be clarifications rather than shifts in how your information is handled.
If you have any questions about this Privacy Policy, reach us at privacy@towerbuildapp.com.
TowerBuild is shaped by the crews who actually use it on the deck.
