# CloudSniff

> CloudSniff is a free read-only diagnostic for Microsoft 365 storage waste.
> It scans OneDrive and SharePoint metadata via Microsoft Graph, surfaces
> version-history bloat, abandoned files, and the worst offenders, and
> translates the result into the monthly dollar number you're paying for
> storage you didn't know you had.

CloudSniff is a Phase 0 hobby project run by an individual founder
(Andrei Antipenko, UAE resident). There is no company, no Stripe
checkout, no paid tier. Donations via GitHub Sponsors and Ko-fi are
optional. Source of truth: https://cloudsniff.space.

## Key pages

- [Home](https://cloudsniff.space/): visibility-first landing, FAQ,
  honest note on Microsoft's native version-cleanup tooling, donation
  links. Sign-in buttons here go directly to Microsoft's OAuth consent
  screen — no intermediate login page.
- [Blog](https://cloudsniff.space/blog): in-depth explainers on
  Microsoft 365 storage, version history, and cleanup tooling. Phase 0
  publishing cadence is roughly 1-2 posts per month.
- [Sign in](https://cloudsniff.space/login): Microsoft Entra ID OAuth
  consent (requests Files.Read.All scope only — read-only).
- [Terms of Service](https://cloudsniff.space/terms): Phase 0 hobby
  terms, AS-IS, no warranty, governing law UAE.
- [Privacy Policy](https://cloudsniff.space/privacy): what metadata is
  collected, where it is stored, 90-day auto-deletion, on-demand delete.

## What CloudSniff does

- Connects to Microsoft 365 via OAuth using the `Files.Read.All` scope
  (read-only) — never write, never delete, never modify.

- Reads file metadata only: names, sizes, dates, version counts,
  owner IDs. Does not download, open, or process file contents.
- Detects version-history bloat: files with hundreds or thousands of
  retained versions accumulated by Microsoft's default 500-version
  retention policy.

- Flags abandoned files: items that haven't been opened or modified
  in a long time and are likely safe candidates for archival.
- Translates raw byte counts into a monthly dollar number based on
  published Microsoft 365 storage tier pricing ($0.20/GB/month for
  SharePoint Extra File Storage).

- Shows the scan as a live animated visualization on the dashboard:
  files stream in as the scan runs, then the picture morphs into the
  final storage breakdown.
- Folder deep-dive: a treemap breakdown of version bloat by folder, so
  the worst directories are visible at a glance, not just the worst
  files.
- The signed-in app UI is available in English and Russian (per-user
  setting). Marketing pages are English-only.

## What CloudSniff does not do

- Does not request `Files.ReadWrite.All` or any write scope. There is
  no in-product cleanup or delete action in Phase 0.
- Does not access the contents of your files, your email, your
  calendar, your Teams chats, or your contacts.
- Does not run subscriptions, recurring billing, or surprise charges.
  Donations are voluntary and one-off.
- Does not have Microsoft Verified Publisher status. Phase 0 has no
  legal entity and no DUNS number — Verified Publisher is a Phase 1
  item that starts only if the project graduates to a real business.
  The consent screen accurately shows "unverified" until then.
- Does not promise to restore deleted versions. Microsoft Graph has
  no undelete primitive for trimmed versions and CloudSniff will not
  pretend otherwise.

## Authority and provenance

- Founder: Andrei Antipenko, UAE-resident IT practitioner, operating
  in personal capacity.
- Funding model: donations only (GitHub Sponsors + Ko-fi). No
  external investors, no paid customers in Phase 0.
- Source code: https://github.com/da-kopman/CloudSniff
- Tone: practitioner-led, transparent about limitations, honest about
  where Microsoft's native tooling already solves the problem.
