TL;DR

  • Antigravity OAuth tokens are exclusive to official Google interfaces — using them with OpenClaw, OpenCode, or any third-party tool is a ToS violation
  • Enforcement is immediate — 403 ToS error with Antigravity access suspended, no prior warning
  • Scope is limited to Antigravity — Gmail and other Google services NOT affected (per Google official statement)
  • Recovery path exists — Varun Mohan confirmed “users not aware… will get a path for them to come back”
  • Safe path: Official Antigravity IDE only; or use Gemini API keys (commercial) for custom tools

Scope

This page covers Google Antigravity terms as of February 2026, with focus on third-party access restrictions. It is a snapshot checklist, not legal advice.

What changed recently

  • February 12-23, 2026: Mass ban wave targeting users who authenticated OpenClaw/OpenCode with Antigravity OAuth tokens. Paying AI Ultra subscribers ($250/month) were suspended without warning.
  • February 22, 2026: Varun Mohan (Google DeepMind) confirmed enforcement was due to “massive increase in malicious usage” that “tremendously degraded quality of service.”
  • February 23, 2026: Peter Steinberger (OpenClaw creator) announced removal of Google Antigravity support from OpenClaw.

Critical ToS clauses

Section 6: Abuse Prevention (Antigravity Additional Terms)

“You must not abuse, harm, interfere with, or disrupt the Service. This includes, but is not limited to, using the Service in connection with products not provided by us.”

Interpretation for engineering teams:

PhraseMeaningConsequence
“products not provided by us”OpenClaw, OpenCode, custom CLI scripts, any third-party toolDetected via User-Agent/binary signature analysis
“using the Service in connection with”Routing Antigravity OAuth through non-Google software403 ToS error + account suspension
“Authorized Application”Official Antigravity IDE or Google interfaces onlyOnly permitted access method

Enforcement Rights

Per Varun Mohan (Google DeepMind engineer, X Feb 22, 2026) and Google DeepMind spokesperson (VentureBeat, Feb 23, 2026):

  • No prior notice required — suspensions are immediate
  • Recovery path exists — “users not aware that this was against our ToS will get a path for them to come back”
  • Scope limited to Antigravity — Google confirms Gmail and other services are NOT affected
  • Billing continues — users report being charged for suspended Antigravity access

Detection Method

Google detects third-party usage through:

  1. User-Agent analysis — identifying non-official clients
  2. Binary signature detection — fingerprinting the connecting software
  3. OAuth token usage patterns — monitoring for anomalous request patterns
  4. Backend load monitoring — “massive increase” in usage triggers investigation

Safe access paths

Terms snapshot checklist (as of Feb 2026)

Third-party access:

  • OAuth tokens are personal-use only — explicitly prohibited in any third-party tool
  • Even research/testing with OAuth tokens violates ToS
  • Detection is automated; enforcement is immediate
  • No warning system before suspension
  • Recovery path exists for “unaware users” (no timeline specified)

Data handling:

  • Antigravity has access to prompts and responses
  • Data retention follows Google’s standard AI product policies
  • Training opt-out available in account settings (verify current status)

Enterprise/commercial use:

  • Gemini API via Google Cloud is the commercial path
  • BAA available for healthcare use cases
  • Vertex AI provides enterprise-grade access

Evidence / signals

  • Official Antigravity Additional Terms of Service
  • Google AI Developer Forum threads documenting ban wave
  • Varun Mohan X post confirming “malicious usage” enforcement
  • Multiple user reports of 403 ToS errors after OpenClaw authentication
  • Google DeepMind spokesperson statement to VentureBeat

How to verify

  1. Read current Antigravity Terms of Service at antigravity.google/terms
  2. Check Google AI Developer Forum for recent policy announcements
  3. If unsure about a tool, assume it’s prohibited unless explicitly listed as authorized
  4. For custom tools, use Gemini API keys instead of OAuth

If your account was affected

  1. Check scope — Verify if only Antigravity is blocked or broader Google services
  2. Contact support — Use Google Cloud Support or [email protected]
  3. Document everything — Save error messages, support ticket numbers, dates
  4. Expect delays — Users report 1-2+ week response times
  5. Prepare alternative — Consider API keys or alternative providers while waiting

⚠️ Data Loss: What Happens to Your Work

Antigravity suspensions can result in lost work — here’s what you need to know.

What’s Lost When Suspended

DataStatusRecovery
Antigravity Chat History❌ INACCESSIBLENo export available during suspension
Code Generated in IDE⚠️ AT RISKOnly saved if manually exported
Connected Project Files✅ SAFEStored in your Google Drive
Gmail/Calendar✅ UNAFFECTEDNormal access continues
Google Drive Files✅ SAFESeparate from Antigravity

The Critical Distinction

Good news: Google’s ban is surgical — only Antigravity is affected:

  • ✅ Gmail works normally
  • ✅ Google Drive is untouched
  • ✅ Calendar, Docs, Sheets all functional
  • ❌ Only Antigravity IDE access blocked

Bad news: Any work only in Antigravity (unsaved code, chat history) is inaccessible during suspension.

Can You Export During Suspension?

No. Once suspended:

  • ❌ Cannot log into Antigravity IDE
  • ❌ No self-service data export
  • ❌ Chat history locked
  • ✅ Project files in Drive remain accessible (if you saved them there)

Protect Your Work NOW

If you’re still using Antigravity:

  1. Save everything to Drive

    • Don’t rely on Antigravity’s workspace
    • Explicitly save files to Google Drive
    • Use “Export to Drive” for generated code

  2. Screenshot critical conversations

    • No chat export feature
    • Copy important code blocks to local files

  3. Switch to Gemini API keys

    • Programmatic access = you control the data
    • Store outputs locally, not in IDE
    • See Google AI Studio

  4. Use local version control

    # Commit anything important immediately

Recovery Timeline Reality Check

StageTimelineYour Data Status
SuspensionImmediateInaccessible
Appeal submittedDay 0-1Still inaccessible
Response1-2 weeksStill inaccessible

If deniedPermanentHistory lost (no export)

Bottom line: If you have critical work in Antigravity, treat suspension as potential data loss. Save locally. Use API keys. Don’t rely on IDE persistence.

  • Official Google announcement of authorized third-party tools list
  • Policy change with warning system implementation
  • Any terms update with new effective date
