Foam Wash Privacy Policy

Effective November 10, 2026

Foam Wash is a mobile app that AeroCore Technologies LLC ("AeroCore", "we") provides to its own employees and contractors to record engine wash work. It is not offered to the public. This policy explains what the app collects, why, and how long it is kept.

Who we are

What Foam Wash collects

1. Your work account. When you sign in with your AeroCore work account (Microsoft), the app receives your name, work email address, your role (for example Technician or Site Lead) and the account and organization identifiers Microsoft provides.
2. Your app settings. Your chosen site, truck, operation and default batch numbers, kept with your account so they follow you to another phone.
3. Work records you enter. Work orders and their details: the customer, the aircraft (such as a registration or aircraft number), the type of wash, times, crew, readings, notes, and quality control decisions.
4. Photos you take for a work order. Photos of the aircraft, engine and wash equipment taken with the phone's camera inside the app. Before a photo is kept as wash evidence or uploaded, the app re-encodes it to remove embedded location data and deletes the camera's temporary original.
5. Device and app details. A random identifier for this installation of the app (never a hardware identifier), linked to your work account, with your phone's platform and operating-system version, the app version, build and update, when the phone first and last contacted our servers, and whether it has work waiting to upload. Authorized AeroCore administrators can see this, and a phone's block history, in Field Management to support the app and to secure lost or stolen phones.
6. Security records. Our servers record account identifiers and access decisions to keep the service secure, and use the network address a request comes from to limit abuse. Microsoft keeps its own records of your sign-ins under AeroCore's Microsoft account.
7. Crash reports. If the app crashes or hits an error, a report is sent to Sentry that contains identifiers and error codes only. It does not contain names, aircraft details, notes or photos.
8. App updates. To deliver app updates and see whether they install, Expo receives your phone's network address, a separate random installation identifier, the phone's platform, the app's version and update channel, and, if an update fails to start, its error details.

Foam Wash does not collect your location, contacts, photo library, microphone or any advertising identifier. It does not show ads, does not track you across other apps or websites, and we do not sell any information from it.

Why we use it

To record and verify wash work, to let site leads review and approve it, to report completed work to AeroCore's systems and its customers, to keep the app working and secure, and to meet our legal and contractual record-keeping obligations.

Who we share it with

• Service providers that run the app for us: Microsoft (work sign-in), Microsoft Azure (hosting and storage), Sentry (crash reports, stored in the United States) and Expo (delivering app updates, as described above). They process information only on our behalf.
• AeroCore's customers receive records of the work done on their own aircraft as part of our service.
• Authorities, when the law requires it.

How long we keep it

On our servers: work orders, quality control decisions, their change history and photos are kept for the life of the record, and at least 7 years. Records of refused uploads are deleted once they are more than 1 year old and every related problem has been resolved. Server request logs are kept 90 days. Crash reports are kept 90 days. Expo deletes its raw request logs, which can contain update error details, after 3 days.

On the phone: unsent drafts stay until you discard them, and work the server refused stays until someone resolves it. A work order is removed from the phone at the next sync after it leaves the server's window, about 14 days after it is approved and locked, or when it is withdrawn; a phone that stays offline keeps it until it syncs. A photo's file is deleted after our server confirms it received the photo and the next sync confirms it. Nothing unsent is deleted automatically, except that when AeroCore blocks a lost or stolen phone, the app erases its Foam Wash data, including unsent work, the next time the phone contacts our servers. Signing out removes the synced work records of the person signing out from the phone.

How we protect it

Work records on the phone are kept in an encrypted database, and photos are kept in the app's private storage, protected by the phone's own encryption. Information sent between the phone and our servers is encrypted in transit. Access is limited by role through AeroCore's work sign-in.

Your choices

You can ask to see or correct information about you by emailing TotalEngineHealth@aerocore.com. Work records are business records, so some cannot be deleted before their retention period ends.

Children

Foam Wash is a work tool for adults and is not directed at children.

Changes

If we change this policy we will post the new version on this page with a new effective date.
