The EU dropped its long-promised ePrivacy Regulation, the UK relaxed some cookie rules while affiliate tracking stayed excluded from that relaxation, and California’s Delete Act brings new data-broker deletion obligations into force in August 2026. None of these changes simplifies affiliate tracking compliance — they mostly narrow the margin for error. Here is what actually changed and what it means operationally.
Quick Answer
What privacy law changes in 2026 affect affiliate tracking compliance?
Three developments matter most: the EU withdrew its long-planned ePrivacy Regulation, leaving the older ePrivacy Directive (enforced country by country) as the operative cookie law, while regulatory guidance has trended toward treating tracking pixels and fingerprinting the same as cookies for consent purposes and narrowing what "legitimate interest" can justify. The UK’s Data (Use and Access) Act created a narrow low-risk-cookie exemption that explicitly excludes affiliate and advertising cookies, which still require consent as before. California’s Delete Act brings new data-broker registration and deletion obligations into force in 2026, requiring covered businesses to engage with a deletion mechanism every 45 days and complete deletions within 45 days of a request, with per-day penalties for non-compliance.
# 2026 Privacy Law Update: What Changed for Affiliate Tracking and What Programs Need to Do
Privacy regulation affecting affiliate tracking didn't get simpler in 2026 — it got more specific, and in several jurisdictions, more strictly enforced. Three developments matter most for programs running tracking pixels, cookies, or affiliate links across US and EU traffic: the EU's ePrivacy Regulation was formally abandoned after years of stalled negotiation (leaving the older ePrivacy Directive, enforced country by country, as the operative cookie law), the UK carved out a narrow exemption for low-risk analytics cookies that explicitly does not extend to affiliate or advertising cookies, and California's Delete Act brings new data-broker registration and deletion obligations into force on a rolling basis through 2026. None of this is abstract policy news for an affiliate program — each of these developments has a direct operational implication for how tracking links, pixels, and consent banners need to work.
The EU: ePrivacy Regulation Is Dead, the Directive Still Governs Cookies
After years of proposed replacement, the EU's ePrivacy Regulation — intended to modernize and unify cookie law across member states — was withdrawn, leaving the older ePrivacy Directive as the operative law, still implemented and enforced somewhat differently country by country rather than through a single unified regulation. For affiliate programs, the practical consequence is continuity rather than a specific new rule: the same fragmented, country-by-country cookie-consent landscape that has existed for years continues, without the unification that the Regulation would have provided. Programs operating across multiple EU member states still need to account for local variation in how consent requirements are interpreted and enforced, rather than assuming a single EU-wide standard applies uniformly.
What has shifted is the scope of what regulators treat as "tracking" subject to consent requirements in the first place. Recent EU guidance has trended toward treating tracking pixels and device/browser fingerprinting the same way it treats cookies for consent purposes — meaning an affiliate tracking pixel that doesn't rely on a cookie at all can still fall inside the same consent obligation that traditionally applied only to cookie-based tracking. A program that assumed moving from cookie-based to pixel-based tracking sidestepped EU consent requirements should not assume that anymore; the compliance obligation increasingly follows the tracking activity itself, not the specific mechanism used to implement it.
Enforcement has also tightened in practice. French regulator CNIL has issued multiple seven-figure fines against publishers for setting advertising cookies before obtaining consent, and EU data protection guidance has narrowed what counts as "legitimate interest" as a legal basis for processing — increasingly limiting it to purposes like security and fraud prevention rather than allowing it as a general justification for attribution or marketing tracking. For an affiliate program, this means the "legitimate interest" basis is a weaker fallback than it may have been treated as in the past; consent, obtained clearly and before tracking begins, is the standard to design around rather than the exception to fall back on when consent seems inconvenient.
The UK: A Narrow Relaxation That Doesn't Cover Affiliate Tracking
The UK's Data (Use and Access) Act made a targeted change that's easy to misread as broader relief than it actually provides: certain low-risk cookies — basic analytics being the clearest example — no longer require prior consent under the revised rules. It's a real simplification for a specific, narrow category of cookie use. But affiliate and advertising cookies are explicitly not included in that relaxation. A UK-facing program that reads headlines about "UK cookie rules relaxed" and assumes its affiliate tracking pixels are now exempt from consent requirements is working from an inaccurate read of the actual scope of the change. The practical guidance for UK traffic remains essentially unchanged for affiliate-specific tracking: consent is still required before affiliate and advertising cookies are set, the same as before the Act.
California: The Delete Act's Data Broker Obligations Come Into Force
California's Delete Act introduces a deletion mechanism that data brokers — a category that can capture more affiliate-adjacent businesses than the "data broker" label might suggest — must actively engage with on a defined cadence. Beginning August 2026, registered data brokers must check the accessible deletion mechanism at least once every 45 days to identify new consumer deletion requests, and must complete deletion of the requested personal information within 45 days of the request being made. This isn't a one-time compliance action; it's an ongoing operational obligation, since a data broker must continue deleting newly acquired information about a consumer who has previously requested deletion, on the same 45-day cadence, for as long as the broker continues acquiring data that could relate to that person.
The registration requirement is also structured to prevent an easy workaround: each data-broker entity must complete its own registration independently, regardless of parent-company or affiliate-network relationships — a business cannot rely on an affiliated or parent entity's registration to satisfy its own separate obligation. Penalties for non-compliance are calculated per day: a failure to process deletion requests within the required window carries a penalty on a per-day, per-request basis, and failure to register at all carries its own separate per-day penalty. Independent third-party audits of data-broker compliance become a requirement in a subsequent phase of the law, adding a further layer of ongoing accountability beyond self-reported compliance.
The practical question for most affiliate programs and publishers is whether the Delete Act's "data broker" definition actually applies to their specific business — a determination that depends on the precise nature of what personal information is collected, shared, and monetized, and is worth confirming directly rather than assuming a program is either clearly in scope or clearly exempt based on how it self-identifies. A publisher or affiliate network primarily focused on referral tracking and commission attribution is a different fact pattern than a business whose core function is aggregating and selling consumer data, but the boundary between those categories is not always obvious from a business's own description of what it does.
What This Means Operationally for Affiliate Programs
Consent-first tracking design, not a legitimate-interest fallback. Across both the EU and UK developments, the direction of travel is the same: affiliate and advertising-related tracking should be designed around obtaining clear, specific, opt-in consent before tracking begins, rather than relying on a legitimate-interest justification that regulatory guidance has been actively narrowing. A consent-management setup that treats "some form of user acknowledgment exists somewhere on the page" as sufficient is increasingly out of step with how enforcement is actually being applied.
Tracking-mechanism-agnostic compliance. Given the trend toward treating pixels and fingerprinting like cookies for consent purposes, a compliance strategy built specifically around "cookie consent" as the frame is incomplete. The more durable frame is consent for the underlying tracking activity, regardless of whether the specific technical mechanism is a cookie, a pixel, or a fingerprinting technique — because regulatory guidance is actively moving toward evaluating the activity rather than the mechanism.
Country-level and state-level variation still matters. The absence of a unified EU ePrivacy Regulation means country-by-country variation in cookie law interpretation remains a real operational factor for multi-market EU programs, not a solved problem. Similarly, US compliance can't be treated as a single national standard — California's Delete Act obligations are specific to California and layer on top of, rather than replace, other state-level privacy law obligations a program may already be tracking.
Affiliate-specific privacy policy language, not a generic template. Any party that collects or processes personal data — which includes affiliates who set their own tracking pixels or cookies — needs a privacy policy that actually discloses that specific activity. A generic privacy policy template that doesn't reference affiliate tracking mechanisms specifically leaves a real gap, particularly given the narrowed legitimate-interest basis and the broadened definition of what counts as trackable activity.
A Practical Compliance Checklist for Late 2026
- Confirm the program's tracking mechanism (cookie, pixel, fingerprinting) is covered by its actual consent flow, not just its cookie banner — given regulatory guidance treating these mechanisms similarly for consent purposes.
- Audit whether any tracking currently relies on legitimate interest as its legal basis, and evaluate moving that tracking to explicit opt-in consent given the narrowing of what legitimate interest is understood to justify.
- Verify UK-facing tracking hasn't been mistakenly treated as covered by the Data (Use and Access) Act's low-risk cookie exemption — affiliate and advertising cookies remain outside that exemption.
- Determine, with actual legal input rather than assumption, whether the program's data collection and sharing activities meet California's data-broker definition, and if so, confirm registration and the 45-day deletion-mechanism engagement cadence are in place ahead of the August 2026 enforcement date.
- Review affiliate-facing privacy policy language for specific disclosure of affiliate tracking activity, rather than relying on a generic template that predates the current guidance on pixels and fingerprinting.
- Reconfirm that any legitimate-interest-based processing is limited to genuinely narrow purposes like security and fraud prevention, consistent with the narrowed scope in EU guidance, rather than being used as a general basis for attribution tracking.
The Bottom Line
None of the individual 2026 developments — the EU dropping the ePrivacy Regulation, the UK's narrow cookie exemption, California's Delete Act obligations coming into force — amounts to a single dramatic rule change that affiliate programs need to react to in isolation. What they add up to, collectively, is a tightening margin for error: consent requirements are being interpreted more broadly (covering pixels and fingerprinting, not just cookies), the legitimate-interest fallback is narrowing, and new obligations like the Delete Act's deletion-mechanism cadence introduce operational requirements with real per-day penalties for non-compliance. Programs that treat privacy compliance as a periodic check-in rather than an ongoing operational discipline are the ones most exposed as enforcement continues to tighten across multiple jurisdictions simultaneously.
Frequently Asked Questions
Did the EU's ePrivacy Regulation get replaced with a new cookie law in 2026?
No — it was withdrawn after years of stalled negotiation, without a replacement. The older ePrivacy Directive remains the operative law governing cookies, implemented and enforced somewhat differently by individual EU member states rather than through a single unified regulation. Programs operating across multiple EU markets still need to account for country-level variation in enforcement and interpretation.
Does the UK's cookie rule relaxation apply to affiliate tracking cookies?
No. The UK's Data (Use and Access) Act created a narrow exemption for certain low-risk cookies, with basic analytics as the clearest example, allowing them without prior consent. Affiliate and advertising cookies are explicitly excluded from that exemption and still require consent under UK rules, unchanged from the prior standard.
What does California's Delete Act require of affiliate-related businesses in 2026?
If a business meets California's data-broker definition, it must register independently (regardless of parent-company or affiliate relationships), engage with the state's accessible deletion mechanism at least every 45 days to identify new consumer deletion requests, complete deletions within 45 days of a request, and continue deleting newly acquired information about a consumer who previously requested deletion on that same ongoing cadence. Non-compliance carries per-day monetary penalties for both late deletion and failure to register. Whether a specific affiliate program or publisher actually meets the data-broker definition depends on the precise nature of its data collection and sharing activity and is worth confirming with legal input.
Is relying on "legitimate interest" still a safe legal basis for affiliate tracking in the EU?
It's a weaker basis than it may have been treated as previously. EU regulatory guidance has narrowed what legitimate interest is understood to justify, increasingly limiting it to purposes like security and fraud prevention rather than general marketing or attribution tracking. The more durable approach is designing tracking around clear, specific, opt-in consent obtained before tracking begins, rather than defaulting to legitimate interest as a justification for affiliate or advertising-related data processing.
