How to Ensure Your BotRefund Bot Detection Setup Is GDPR Compliant

BotRefund acts as a data processor when it collects hardware fingerprints, network signals, and interaction patterns to decide whether a visit is human or automated. Under the GDPR, you remain the controller. That means you must define the lawful basis, limit retention, inform visitors, and honor data‑subject requests. The steps below walk through each obligation using BotRefund’s own architecture — 106 independent checks, cross‑checked evidence, and an AI model that weighs the full pattern instead of relying on a single rule.

Understand BotRefund’s Role in Your Data Flow

BotRefund’s detection runs client‑side in the visitor’s browser. It gathers hardware and GPU fingerprints, CPU concurrency data, network port behavior, mouse‑movement patterns, click timing, and session duration. Each signal — such as the CPU Concurrency Lie check or the Suspicious Ports check — is recorded as independent evidence, not a final verdict. The platform then cross‑checks all signals and feeds them into an AI prediction model that reaches 99% accuracy by evaluating the complete picture. Because this processing happens on your behalf, you need a Data Processing Agreement (DPA) with BotRefund that covers the categories of personal data (device identifiers, IP address, behavioral metadata), the purpose (fraud prevention and ad‑spend protection), and the security measures BotRefund applies.

Configure Data Retention and Minimization Settings

The GDPR requires you to keep personal data only as long as necessary. BotRefund’s dashboard lets you set retention windows for raw signals and for the AI‑scored verdicts. A practical starting point: retain raw browser and network signals for 30 days (enough to support a refund claim with Google or Meta) and keep the final bot/human classification for 90 days to support audit trails. Delete or anonymize anything older automatically. If you operate in a sector with longer statutory retention (e.g., financial services), document the legal requirement and adjust the window accordingly — but never keep data “just in case.”

Document Your Lawful Basis and Update Your Privacy Policy

Most companies rely on legitimate interest (Article 6(1)(f)) for fraud prevention and ad‑spend protection. Write a short Legitimate Interest Assessment (LIA) that explains: (1) the interest — stopping bots that waste up to 20% of Google and Meta ad budgets; (2) the necessity — BotRefund’s 106 cross‑checked signals are the least intrusive way to achieve that accuracy; (3) the balancing test — visitors’ privacy impact is low because BotRefund treats each signal as evidence, not a verdict, and does not build persistent profiles. Then update your privacy notice to name BotRefund as a processor, list the data categories (device fingerprint, IP, interaction telemetry), state the purpose, retention periods, and the visitor’s right to object.

Inform Visitors About Bot Detection Processing

Transparency means telling people before the script runs. Add a concise notice in your cookie banner or privacy overlay: “We use BotRefund to detect automated traffic and protect our advertising budget. It analyzes browser, device, and interaction signals. You can object in the privacy settings.” Link to the full privacy policy section. If you serve users in the ePrivacy Directive zone (EU/EEA), treat the BotRefund script as non‑essential and require prior consent unless your national regulator has clarified that fraud‑prevention scripts fall under the “strictly necessary” exemption. When in doubt, ask for consent — it also strengthens your LIA.

Implement Data‑Subject Rights Workflows

Visitors can request access, rectification, erasure, restriction, or portability of the data BotRefund processes on your behalf. Build a simple internal process: (1) receive the request via your privacy email or form; (2) verify identity proportionally; (3) query BotRefund’s API or dashboard for any stored signals tied to that visitor’s pseudonymized ID; (4) respond within 30 days. Because BotRefund does not store names or emails — only browser‑level identifiers — most requests will resolve to “no directly identifiable data held.” Document that outcome. If a visitor objects to processing, you can either suppress their session from BotRefund (if your integration supports a do‑not‑track flag) or exclude their traffic from ad‑platform refund claims.

Verify Cross‑Border Transfer Safeguards

BotRefund’s infrastructure may process data outside the EEA. Confirm the transfer mechanism in your DPA: Standard Contractual Clauses (SCCs) supplemented by a Transfer Impact Assessment, or an adequacy decision if the data stays in an approved country. Ask BotRefund for their current sub‑processor list and the location of each. If a sub‑processor changes, your DPA should require notification so you can update your records and, if needed, your privacy notice.

Common Compliance Gaps to Avoid

• No DPA signed: Without a written processor agreement, you are in breach of Article 28.
• Indefinite retention: Keeping raw signals forever “for future AI training” violates storage limitation.
• Missing objection path: If a visitor cannot easily opt out, your legitimate‑interest balance tips against you.
• Vague privacy notice: “We use analytics” does not cover device fingerprinting and behavioral scoring.
• Ignoring sub‑processors: BotRefund may use CDN or cloud providers; you must know where data flows.

FAQ

Does BotRefund set cookies or use local storage?

The detection script runs in memory and may write a short‑lived identifier to local storage to correlate signals within a session. Treat that identifier as personal data under the GDPR and include it in your retention and deletion workflows.

Can I use BotRefund without consent under the ePrivacy Directive?

Some EU regulators consider fraud‑prevention scripts “strictly necessary” for a service the user requested (ad‑funded content). Others require consent. The safest route: ask for consent in your banner and log the choice. If you rely on the exemption, document your reasoning and be ready to show it to a supervisory authority.

What personal data does BotRefund actually see?

BotRefund processes device fingerprints (GPU, CPU, fonts, audio stack), IP address, network port behavior, mouse‑movement coordinates, click timestamps, scroll depth, and session length. It does not collect names, emails, or CRM identifiers unless you explicitly pass them — which you should not do.

How do I handle a “right to be forgotten” request for a visitor I cannot re‑identify?

If the visitor supplies a session ID or approximate time/URL, query BotRefund’s dashboard for that pseudonymized ID and delete the associated signals. If they cannot provide any identifier, respond that no directly identifiable data is held and that pseudonymized signals are auto‑expired per your retention schedule.

Does BotRefund’s AI model train on my visitors’ data?

BotRefund’s 99% accuracy comes from a global model trained on aggregated patterns. Your visitors’ raw signals are used for real‑time scoring, not for retraining the model on your account. Confirm this in the DPA and ensure the contract prohibits using your data to improve the shared model without your consent.

What if BotRefund adds a new detection signal?

Treat any new signal as a change in processing. Update your DPA, privacy notice, LIA, and retention schedule. Notify visitors if the new signal materially changes the privacy impact (e.g., adding audio fingerprinting).

Can I run BotRefund only on paid‑traffic landing pages to reduce scope?

Yes. Limiting the script to pages that receive Google or Meta clicks reduces the data volume and strengthens your necessity argument. Configure the snippet to load conditionally based on UTM parameters or referrer headers.
