ePlan Privacy Policy

Effective date: 17 October 2026

ePlan is an app for electricians to annotate floorplans with electrical symbols and wiring, and to share those plans with teammates. This policy describes what data ePlan stores and how it is used.

Data we store

• Account details: your name and email address, provided by Sign in with Apple or Google when you create your account.
• Project content: the floorplans you import and the symbols, wires, and notes you place on them, so they can sync between your devices and any teammates you share a project with.
• Device details: the platform and app version, the operating system version, the device model (Android) or browser (web), your language setting, the country your connection came from, the symbol style, measurement units and region your device is set to, whether it can scan rooms, and which of our server addresses it reached, noted when you last used the app.
• Usage data: which parts of the app you use and when (for example opening a plan, drawing walls or wires, running a test, exporting a PDF), how long the app and a plan stay open, and what fails on your device (a sync, an import, an export, a purchase). It is linked to your account and never includes the content of your plans. Each record is deleted after 90 days.
• Failure records: when a request from the app to our server fails, we record the time, the kind of request, the error, and the account it came from, so that we can find the fault and contact you if it affected your work. These records are deleted after 30 days.
• Backups: copies of our database and of uploaded floorplans, kept so that data lost to a fault can be restored. A deleted or replaced floorplan is held in a deletion area for 90 days, then permanently deleted; daily copies of the database are kept for 90 days and monthly copies for a year. Content you delete, and a deleted account, disappear from these copies on that schedule.

This data is stored on Cloudflare infrastructure (Cloudflare Workers, D1, and R2). It is used only to provide the app's functionality and, in the case of device details and usage data, to see which parts of ePlan are used and where it fails, so that we can improve it: we do not sell it, use it for advertising, or share it with third parties beyond the infrastructure that hosts it.

Subscriptions

The ePlan Premium subscription is billed entirely by Apple through your App Store account, or on Android by Google through your Google Play account. ePlan never sees or stores your payment details; we record only the subscription's expiry so premium features can be unlocked, on Android the Google Play purchase token that lets us confirm the subscription with Google, and, for 30 days, a note when Apple tells us a purchase was refunded.

Sharing

When you join a project by invite, the project's members can see your name and email as a member, along with the plans and edits in that project.

Questions and deletion requests

Deleting your account in the app (account menu, Delete Account) removes all of the above, including usage data. For any questions about your data, or to request deletion of your account and its content, contact bodiud@tcd.ie.
