Stringer Privacy Policy

Information You Enter

You may enter project names, total rise, going (tread run), available run limits, building code selection, construction settings (standard or flush, layout, nosing, tread thickness, dropped stringer), stringer stock size, stair width, stock price for estimates, unit preferences, and notes. This information is used only to calculate stair options and generate stringer layouts and cut sheets inside the app.

Local Storage

Your saved projects, stair dimensions, code and construction settings, calculated options, and generated cut sheets are stored locally on your device. If you remove the app, this locally stored data may be deleted unless it is included in Apple-managed device backups.

Offline Operation

The core workflow for entering dimensions, calculating riser and tread options, previewing the elevation and stringer drawings, checking code compliance, and saving projects does not require an internet connection. We do not operate a customer account system, cloud sync service, or remote project storage service for Stringer.

Exporting and Sharing

When you choose to export, print, or share a cut sheet or stair drawing, the selected content is passed to the iOS sharing, printing, or export option you explicitly invoke. The destination printer, app, or share target may process that information according to its own policies.

Building Code Information

Code references such as IRC, NCC, and Doc K are provided inside the app for general estimating and planning support only. Compliance results shown in the app are estimates. You are responsible for verifying measurements, headroom, and local code and permit requirements with a qualified professional before building.

What We Do Not Sell

We do not sell your personal information. Stringer is not designed around advertising profiles, third-party data brokerage, analytics tracking, or social networking features.

Permissions

• On-device storage: used to save projects, stair dimensions, settings, and calculated layouts.
• Export, print, and share sheet: used only when you choose to export, print, or share a cut sheet or drawing.
• Apple-managed backups: controlled through your Apple account and device settings.

Data Retention and Deletion

You can delete saved projects, stair designs, and cut sheets from within the app. You may also remove the app from your device to delete locally stored data, subject to any Apple-managed backups you have enabled.

Disclaimer and Limitation of Liability

Stringer is provided for general informational, estimating, and planning purposes only. Stair calculations, code checks, diagrams, material estimates, prices, and cut sheets are generated from the information you enter and may be incomplete, inaccurate, or unsuitable for your specific project, site conditions, materials, tools, or local building requirements.

Stringer does not provide professional, structural, engineering, architectural, construction, safety, legal, or code-compliance advice. Before building, cutting, installing, permitting, or relying on any stair design, you are responsible for independently verifying all measurements, rise and run values, headroom, landings, guards, handrails, stringer sizing, fasteners, loads, and applicable local codes with a qualified professional or local authority.

The app and its content are provided on an "as is" and "as available" basis without warranties of any kind. To the maximum extent permitted by law, JiaBao Dai and WoodCutTool are not liable for any loss, injury, damage, code violation, failed inspection, construction defect, material waste, project delay, or other consequence arising from your use of, or reliance on, Stringer calculations, drawings, exports, or cut sheets.
