Terms of Service

GamPacto is a free Chrome extension designed to help you reduce exposure to gambling content. It provides three layers of protection:

• Layer 1 — Domain blocklist. An on-device list of around 46,000 known gambling domains, drawn primarily from authoritative sources such as the UK Gambling Commission register. Matches are blocked instantly with no network call.
• Layer 2 — Smart detection. An on-device heuristic scan analyses page content for gambling signals. Borderline pages are sent to an AI classifier (a short text excerpt only) for a final verdict. AI classification is available to everyone, with or without an account.
• Layer 3 — Accountability partner. Optional. A trusted person you nominate receives discreet notification emails when gambling is detected on your browser — only date and time, never URLs or content.

Other optional features include sensitivity tiers (Strict/Balanced/Light), a 24-hour cool-off when weakening protection, a detailed-history opt-in for signed-in users, and a multi-sheet Excel export of your detection data.

You must be at least 13 years old to use GamPacto. If you're under 18, we recommend having a parent or guardian's consent before installing.

An account is entirely optional. The blocklist, on-device detection, and AI classification all work without one — anonymous users are rate-limited per browser installation rather than per user, and the daily allowance is identical to a signed-in user's. What an account unlocks is personalisation:

• Sensitivity tier (Strict / Balanced / Light) — the choice follows you across browsers if you sign in elsewhere.
• Detailed history opt-in — the option to keep per-event detection records (URL, hostname, evidence) on your device. Off by default; you can switch it back off and clear stored detail at any time.

If you create an account:

• Keep your login credentials safe — you're responsible for activity under your account.
• Use accurate information when signing up. We use the email only for authentication, password reset, and (if you add a partner) to notify you when partner-related events occur.
• We may suspend or close accounts that violate these terms.
• You can delete your account and all associated server-side data at any time by emailing privacy@gampacto.com. See “Termination” below for what gets deleted and the timing.

GamPacto is for personal gambling harm reduction. Please don't:

• Use it to probe or test gambling website security.
• Reverse engineer or modify the extension for malicious purposes.
• Abuse the AI classification feature, automate it from a script, or attempt to exceed the daily rate limit by spinning up new installations.
• Add an accountability partner who has not actually agreed to receive these notifications. The 6-digit verification step is your partner's consent — please don't try to circumvent it.
• Use the extension in any way that breaks applicable laws.

When the on-device detector flags a page as borderline or high-confidence-gambling, GamPacto sends a short text excerpt (around 500 characters of visible page text), the page URL, and the page hostname to our backend for AI classification by Anthropic's Claude. The verdict is returned to your browser and stored locally. This happens whether or not you have an account.

By using this feature:

• You consent to those short excerpts being transmitted for classification.
• You understand AI isn't perfect — false positives and false negatives can happen. We expose a “This page isn't gambling” option on the block overlay (only when the AI's own confidence is below 95) so you can override and add the URL to a 14-day local whitelist.
• There is a fair-use limit of 100 classifications per day. For signed-in users this is per-account; for anonymous users it is per-installation, tracked via a random anonymous identifier stored in your browser. The limit applies equally to both.
• The page excerpt is processed in memory by the AI model and is not retained on our servers after the response is returned.
• We do not use any data sent for AI classification to train or fine-tune machine-learning models.

This feature lets you designate a trusted person to receive discreet notification emails when GamPacto's protection-related events occur on your browser. By using it:

• Consent is built into setup. When you add a partner, GamPacto sends a 6-digit verification code to their email address. They start receiving notifications only after they enter that code — the code is the partner's consent.
• Notification emails contain only date and time for detection events. They never include URLs, hostnames, page content, or any browsing details.
• The partner is also notified about protection-weakening choices. If you request to lower your sensitivity tier, your partner is told the moment you ask, the cool-off duration, and when the change will take effect. If you cancel a queued change, or upgrade to a stricter tier, the partner is notified of that too. The point is to set up an external commitment before the change is applied.
• Two unsubscribe paths. You can remove your partner from the popup at any time, which stops all future notifications instantly and removes their email from our database. Your partner can also request to be unsubscribed by emailing privacy@gampacto.com; we will remove them within seven days and tell you they have opted out.

Signed-in users can choose one of three sensitivity tiers:

• Strict (default for new accounts) — the AI classifier is more inclined to flag, and more pages are routed to it.
• Balanced — standard thresholds.
• Light — fewer pages are routed to AI, and the AI is more inclined to allow.

Choosing a stricter tier (e.g. Light → Balanced or Balanced → Strict) takes effect immediately. Choosing a less strict tier is queued with a deliberate cool-off:

• Strict → Balanced or Balanced → Light: 24 hours.
• Strict → Light: 48 hours.

During the cool-off the change is visible in the popup with a live countdown and a Cancel button. If you've added an accountability partner, they are notified the moment you request the change — not when it takes effect — so the external commitment is in place before the change applies. This is a deliberate harm-reduction design choice, not a bug.

By default, GamPacto stores only aggregate counters on your device — how many times each detection layer fired, daily totals, AI confidence buckets — never URLs, hostnames, or evidence text. This is true for everyone, including signed-in users.

Signed-in users can optionally turn on Detailed history from the Blocklists tab in the popup. When enabled, GamPacto additionally stores per-event records (URL, hostname, confidence score, matched evidence) for the most recent 500 detections. Those records live only on your device and never reach our servers.

You can switch Detailed history off again at any time, which stops new per-event entries; existing entries stay until you clear them. The Clear button in the same section wipes all per-event detail with one click while leaving the aggregate summary intact (so your dashboard stats survive). Logging out automatically forces Detailed history off.

You can download all of your locally-stored detection data as a multi-sheet Microsoft Excel (.xlsx) workbook from the Blocklists tab. The file always includes:

• A Summary sheet with totals, breakdowns by detection layer / result / category, AI confidence buckets, and the last 14 days of daily counts.
• An AI whitelist sheet listing pages you marked as safe and their auto-expiry dates.
• Your domain blocklist and Your URL blocklist sheets if either contains entries.

If Detailed history is enabled, the workbook also includes one sheet per detection category (each containing the per-event records: timestamp, hostname, URL, confidence, evidence). If Detailed history is off, those category sheets are absent and only aggregate counts are exported. The Summary sheet labels which mode produced the file.

The export is generated entirely in your browser; nothing is uploaded to produce it.

GamPacto is provided “as is.” We do our best, but we can't guarantee:

• Every gambling site will be caught — some may slip through detection.
• The extension will always be error-free or uninterrupted.
• AI classification will always be available or accurate, or that the daily allowance will always be sufficient for your usage.
• Compatibility with every website or Chrome version. The extension is currently in developer-mode pre-release (version 0.1.0) and has not yet been published to the Chrome Web Store.

By design, GamPacto does not surface non-blocking warning banners for borderline content — pages either get blocked or pass silently. If you see gambling content that wasn't blocked, the heuristic and AI judged it to be below the gambling threshold, or the page changed since it was last classified.

To the extent allowed by law, we're not liable for damages arising from detection failures, false positives, service interruptions, or account compromises due to credential mishandling.

Intellectual property: All GamPacto content, design, code, and branding belong to its developers. Don't reproduce or create derivative works without written permission.

Termination by you (no account). Uninstalling the extension removes all locally-stored data — detection summary, any per-event detail you opted in to keep, AI whitelist, your blocklists, preferences, and the random installation identifier used for anonymous rate limiting.

Termination by you (with an account). Uninstalling the extension removes the local data described above. Your account, sensitivity preference, and any accountability-partner email stored on our servers remain until you request deletion. To delete them, email privacy@gampacto.com from the address associated with your account, with subject line “Delete my account.” We will hard-delete the relevant rows within 30 days; database backups are rotated within the same 30-day window. You will receive an email confirmation when the deletion is complete. Full details are in our Privacy Policy.

Termination by us. We may suspend or close accounts that violate these terms. We will tell you why if we do.

Changes: We may update these terms occasionally. Material changes will be reflected in the effective date at the top. If you have an account, we will email you ahead of material changes. Continued use after changes means you accept the updated terms.

Governing law: These terms are governed by the laws of England and Wales, with disputes subject to the exclusive jurisdiction of courts in England and Wales.
