Slope Privacy Notice

Slope's analysis engine runs entirely in your web browser. Your model geometry, soil parameters, groundwater conditions, loads, reinforcement, analysis settings, and results are calculated locally rather than on hetGE's servers. A local-only model remains in your browser and in files you choose to export. When you open or save an account-bound cloud design, its model inputs, saved results, summary, and thumbnail are transmitted to hetGE for storage and cross-device synchronization.

• Sign-in: authentication is handled by hetGE Account (account.hetge.com) using secure, httpOnly session cookies. See the hetGE Account Privacy Policy for how account data is processed.
• License verification: the application periodically confirms your license status (license identifier and expiry) with hetGE Account.
• Cloud workspace: project metadata, designs, saved analysis data, thumbnails, personal material and reinforcement libraries, and optional project cover images are stored for your account. Design calculations still execute in your browser.
• Server logs: like every web service, our servers record standard technical logs (IP address, timestamp, requested URL, user agent) for security and operations.
• Usage statistics: while your hetGE account's "Share usage statistics" switch is on (it is on unless you turn it off), Slope reports to hetGE Account which actions you took — that an analysis or a probabilistic run completed, and with which method and search kind; that a report was generated; that a design was created, opened, or imported; and that coordinates were pasted into the editor — plus how long the editor was actively used, meaning visible, focused, and in use. No content of your work is ever sent this way: no names, values, coordinates, or any other free text of your design leaves your browser. Your IP address and browser user agent are passed along only so hetGE Account can form that day's per-browser record in its statistics service (Umami) and work out your country; neither is stored. See the hetGE Account Privacy Policy for how it handles what it receives.

Slope contains no advertising or third-party tracking cookies. Usage statistics set no cookies either. Your browser's Global Privacy Control or Do Not Track signal stops it, and so does turning "Share usage statistics" off on your hetGE account.

Slope stores working data under keys beginning with com.hetge.slope- in local storage and keeps cached cloud designs and pending saves in IndexedDB. Local settings, preferences, undo history, and your acceptance of the Terms remain on the device. Cloud-design payloads are synchronized with hetGE; clearing browser data removes only the local copies and does not delete their cloud copies. Project files you export are ordinary files under your control.

Your hetGE account (profile, credentials, purchases) is operated by hetGE Account and governed by its Privacy Policy at account.hetge.com/privacy.
