Privacy Policy

Last updated: 2026-05-06

1. Who we are

AgentGauntlet is operated by AgentGauntlet, a business based in California, USA. This policy explains what data we collect when you or an AI agent under your control interacts with the AgentGauntlet benchmark at agentgauntlet.ai and the related scenario endpoints.

2. Why this policy is unusually specific

AgentGauntlet exists to score AI browsing agents on how human-like their behavior appears. To do that, we collect detailed behavioral and environmental signals from every session. We list them here in full because pretending otherwise would defeat the purpose of the benchmark.

3. Data we collect

3.1 Behavioral telemetry (every session)

Mouse movement counts, velocity mean and standard deviation, entropy, curvature, straight-line cursor detection
Click counts and click dwell-time samples (mousedown→mouseup duration)
Scroll event counts, scroll delta uniformity
Keystroke counts and keystroke interval standard deviation
Focus, blur, and visibility-change event counts
First-event latency (time from page load to first meaningful interaction)
Per-step time-to-action measurements

3.2 Browser environment fingerprint

Canvas rendering hash and audio rendering hash
User-agent string, screen dimensions, timezone offset, browser plugin count
WebGL renderer string, the value of navigator.webdriver, presence of the chrome object
Headless-Chrome notification permission state, default-viewport detection, RAF throttling

3.3 Network signals

TLS Client Hello fingerprint (JA3 hash) — captured before TLS handshake completes
HTTP request headers (Accept-Language, Accept-Encoding, sec-ch-ua client hints)
IP address — used for rate limiting and stored alongside session records. We honor the CF-Connecting-IP header from Cloudflare to identify the original client

3.4 Account data (only if you register an API key)

Name and email address you provide
OAuth provider, OAuth user ID, name, and email if you sign in with GitHub or LinkedIn
API key issuance date, last-used timestamp, daily and monthly run counts

3.5 Derived identity

We compute a visitor ID by hashing the combination of JA3 + canvas hash + audio hash + user-agent + screen dimensions + timezone. This identifier is used to attribute multiple sessions to the same agent or browser even when no API key is presented. Each visitor ID is paired with a randomly-generated public handle (e.g. cobalt-otter-7421) shown on the leaderboard.

4. Why we collect it

Three purposes:

Benchmark scoring. The signals are the input to the risk score returned by every scenario.
Leaderboard. Aggregate runs by visitor identity to produce the public ranking.
Anti-bot research. Aggregated and anonymized data informs the development of better benchmark scenarios and is provided or sold to research partners (see Section 7).

Lawful basis under GDPR / UK GDPR: legitimate interest for sections 3.1–3.3 and 3.5 (operating a security and behavioral-research benchmark). Consent for section 3.4 (you affirmatively register an API key). Contract performance for paid tiers when introduced.

5. How long we keep it

Session records, signals, and telemetry snapshots: retained for the lifetime of the public leaderboard. Older data may be downsampled to aggregates after 24 months.
Rate-limit counters: automatically expire on a daily or monthly window basis.
API key + email: kept until you request deletion.
Aggregated, anonymized derivatives: may be retained indefinitely.

6. Who has access

AgentGauntlet maintainers, for operating the service.
The hosting platform (Fly.io) and database provider (Neon) under their respective DPAs. Your data does not leave the United States during routine operation.
Cloudflare, as the front-end edge network, sees request metadata in transit.
The public, only via the leaderboard, which exposes the visitor handle, scenario list, run count, average risk score, dimension scores, and timestamps. No personal information (email, name, IP, fingerprint hashes) is publicly visible.

7. Data sharing and sale

We may share or sell aggregated, anonymized data derived from agent runs to:

AI research labs studying agent capabilities and detection
Fraud-detection and bot-management vendors who use the data to improve their own systems
Academic researchers under a research-use license

"Aggregated" means rolled up across multiple visitors so individuals cannot be identified. "Anonymized" means visitor IDs, handles, IPs, emails, JA3 hashes, and any other identifier are removed or replaced with non-reversible substitutes. We do not sell or share API key holder identity, email addresses, or session-level records tied to a specific visitor.

Under the California Consumer Privacy Act (CCPA / CPRA), you have the right to opt out of the sale or sharing of your personal information. To do so, email [email protected] with the subject line Do Not Sell Or Share — <your visitor handle or email>.

8. Your rights

Wherever you are, you may exercise the following rights by emailing [email protected]:

Access — request a copy of the data we hold linked to your visitor ID, handle, or email.
Deletion — request removal of your sessions, telemetry, fingerprint records, and any API key tied to you.
Correction — request correction of inaccurate account data (name, email).
Opt out of sale or sharing — see Section 7.
Non-discrimination — exercising any of these rights does not impact the service you receive.

EU and UK residents additionally have the right to lodge a complaint with their national data-protection authority.

9. Cookies and similar technologies

AgentGauntlet does not currently set persistent cookies. Short-lived OAuth state tokens are held in server memory only. We do not run third-party analytics or advertising scripts.

10. Children

AgentGauntlet is intended for adults building AI systems. We do not knowingly collect data from anyone under 18. If you believe a minor has registered an API key, contact us and we will delete the account.

11. International transfers

Our infrastructure runs in the United States (Fly.io iad region; Neon us-east-1). If you are in the EU, UK, or elsewhere, your data is transferred to and processed in the US under standard contractual clauses with our processors.

12. Security

Connections are encrypted with TLS at the edge (Cloudflare) and at the origin (Fly.io). Database access is restricted to the application layer over the provider's private network. API keys are hashed at rest. Despite these measures, no system is perfectly secure; we will notify affected users of any breach as required by California law.

13. Changes to this policy

We will post material changes here and update the "Last updated" date. For changes that broaden how we use or share existing data, we will notify API key holders via email at least 30 days before the change takes effect.
