Which Smart Plug Platforms Respect Your Privacy? A Vendor Scorecard

If your smart plug can turn your coffee maker on from the office, it can also spill data about your home — unless you choose carefully.

Smart plugs are one of the easiest ways to automate a home, but they’re also one of the most common IoT devices that leak data by default. This 2026 vendor scorecard rates the major smart plug makers on five privacy-critical axes: local control, default telemetry, GDPR/CCPA (data rights) posture, clarity of privacy documentation, and firmware & update transparency. Use this guide to buy a smart plug that respects your privacy — or harden one you already own.

How we scored vendors (methodology)

Our evaluation reflects lab work and policy review done in late 2025 and early 2026. For each vendor we assigned 0–5 points in five categories and published a plain-language justification. Scores reflect the device as shipped with default settings and firmware available at the time of review; many vendors offer opt-outs, beta features, or Matter/HomeKit variations that change privacy behavior.

• Local control (0–5) — Can the plug operate without the vendor cloud? Matter/HomeKit over local IP/Thread counts. Scores lower if cloud dependency is required for basic on/off or schedules.
• Default telemetry (0–5) — What data the device phones home with default settings: basic health pings vs. telemetry-rich analytics. Higher is better (less telemetry).
• GDPR/CCPA posture (0–5) — Does the vendor provide clear mechanisms for EU/California rights: data access, deletion, portability, and a named DPO or contact?
• Clarity of privacy docs (0–5) — How readable, specific, and transparent the privacy policy and FAQ are about telemetry, retention, and sharing.
• Firmware & update transparency (0–5) — Are firmware updates signed and documented? Can users verify or install alternative firmware (for advanced users)?

We weighted local control and default telemetry more heavily in our overall recommendation because they most directly affect day-to-day privacy.

2026 Context: Why this matters now

By 2025 many smart-plug vendors shipped Matter-capable models or pledged support — a big step for local control because Matter enables direct, on-network control via a hub. At the same time, regulators continued to raise the bar: the EU’s enforcement of GDPR and increasing U.S. state-level privacy rules (CPRA-style amendments, VCDPA-like laws in multiple states) mean vendors can no longer bury telemetry practices in fine print without consequences; see recent updates to consumer rules and enforcement trends at consumer rights law.

That said, adoption is mixed. Some brands embraced privacy-by-default and shipped minimal telemetry settings; others leaned into cloud features and analytics. This scorecard helps separate marketing claims ("local mode available") from default behavior and real-world privacy posture.

Smart Plug Privacy Scorecard (Jan 2026 snapshot)

Below are 10 widely available smart plug vendors scored on the five axes. Each vendor block includes the raw sub-scores, a short rationale, and practical steps you can take if you own that brand.

Eve Energy — Overall: 24/25

• Local control: 5 — Native HomeKit/Matter local control without required cloud.
• Default telemetry: 5 — Minimal default telemetry; focused on local operation.
• GDPR/CCPA posture: 5 — Clear data subject mechanisms and EU presence.
• Clarity of docs: 4 — Policy is readable and specific; could improve technical detail.
• Firmware transparency: 5 — Clear update notes, signed firmware, and a track record for security patches.

Why this score: Eve is the benchmark for privacy-first smart home accessories in 2026. If you want plug-and-play privacy with minimal networking tinkering, Eve’s Matter/HomeKit-first approach is the easiest route.

Practical tip: Use HomeKit or a Matter controller set to local-only. Disable any optional cloud features when prompted.

TP-Link (Kasa / Tapo Matter models) — Overall: 18/25

• Local control: 4 — New Matter models (P125M and others) enable local control; legacy Kasa/Tapo models often default to cloud.
• Default telemetry: 3 — Moderate telemetry by default on older models; Matter models reduce cloud dependency.
• GDPR/CCPA posture: 4 — Decent controls for EU/CA, though request processes can be slow.
• Clarity of docs: 3 — Policies present but sometimes generic about analytics.
• Firmware transparency: 4 — Regular updates; signing practices improved in 2025 but varied by product line.

Why this score: TP-Link made strong progress in 2024–2025 shipping Matter-capable plugs. If you buy a Matter-certified TP-Link model and register it to a local hub, you can eliminate most cloud telemetry.

Practical tip: Buy the Matter-certified SKU, update firmware immediately, and pair through your chosen hub (Home Assistant, HomeKit, or a Matter controller) rather than the vendor app.

Belkin Wemo — Overall: 16/25

• Local control: 4 — Wemo introduced Matter support and improved local operation for core features.
• Default telemetry: 3 — Default settings include telemetry for diagnostics; opt-out available but not prominent.
• GDPR/CCPA posture: 4 — Reasonable rights and public privacy contacts.
• Clarity of docs: 3 — Policies readable but lack low-level telemetry lists.
• Firmware transparency: 2 — Firmware updates are frequent but not granularly documented; signing practices could be clearer.

Why this score: Wemo’s Matter rollout in 2025 improved local control, but some older models still default to cloud services. Confirm the SKU and firmware before assuming local-only operation.

Wyze — Overall: 13/25

• Local control: 2 — Many Wyze plugs rely on cloud services by default; local modes are limited and device-dependent.
• Default telemetry: 2 — Historically higher telemetry for product improvement; some opt-out controls added in 2025.
• GDPR/CCPA posture: 3 — Mechanisms exist but processes can be slow for complex requests.
• Clarity of docs: 3 — Policies are public but technical transparency is limited.
• Firmware transparency: 3 — Occasional documentation on updates; community solutions exist for some models.

Why this score: Wyze is budget-friendly and feature-rich but remains cloud-oriented. You can reduce exposure with network-level controls, but expect vendor telemetry on default builds.

Sonoff / ITEAD — Overall: 15/25

• Local control: 3 — Stock firmware uses cloud; many Sonoff models are flashable to run Tasmota/ESPHome for local control.
• Default telemetry: 2 — Stock firmware phones home; community firmware eliminates telemetry.
• GDPR/CCPA posture: 3 — Basic compliance steps but limited EU-specific tooling.
• Clarity of docs: 3 — Mixed; product pages list features but privacy-specific language is short.
• Firmware transparency: 4 — Community and vendor ecosystems support aftermarket firmware; official firmware signing varies.

Why this score: Sonoff is great for DIYers. If you are comfortable flashing devices, you can convert a low-cost Sonoff plug into a local-only device with strong privacy. If you don’t flash, expect cloud telemetry.

Practical tip: If you flash, follow up-to-date flashing guides, verify firmware checksums where available, and keep a recovery plan in case of a bricked device.

Meross — Overall: 14/25

• Local control: 2 — Many Meross plugs default to cloud and have limited local APIs.
• Default telemetry: 2 — Moderate telemetry that includes usage and diagnostics by default.
• GDPR/CCPA posture: 4 — Clear contact info and basic rights mechanisms.
• Clarity of docs: 3 — Documentation exists but lacks detail on telemetry categories.
• Firmware transparency: 3 — Periodic updates; signature and changelog practices have improved but remain inconsistent.

Why this score: Meross is convenient and affordable; in 2025 they announced better GDPR processes, but their devices still default to cloud-first behavior.

Aqara — Overall: 17/25

• Local control: 4 — Zigbee-based Aqara hubs support local automations; Matter models improved direct local control in 2025.
• Default telemetry: 3 — Some telemetry retained by cloud services for remote access; local hub operation minimizes exposure.
• GDPR/CCPA posture: 4 — Clear policies and EU presence; some Xiaomi-related concerns remain among privacy-conscious buyers.
• Clarity of docs: 3 — Generally clear but occasionally sparse on technical retention details.
• Firmware transparency: 3 — Regular patching, but visibility into signing is mixed across SKUs.

Why this score: Aqara is a good pick if you run a local Zigbee hub. Using the hub's local automations keeps data inside your network even when remote access options are enabled.

Tuya-based OEMs (Gosund, Teckin, Generic) — Overall: 9/25

• Local control: 1 — Most Tuya-sourced plugs are cloud-dependent unless explicitly offered as a locally integrated variant.
• Default telemetry: 1 — High default telemetry; many models collect analytics and usage metrics.
• GDPR/CCPA posture: 2 — Basic mechanisms exist for EU/CA but execution varies by OEM and region.
• Clarity of docs: 1 — Policies are often generic, sometimes hard to locate or translated poorly.
• Firmware transparency: 4 — Hardware often compatible with community firmware, but warranty and ease vary.

Why this score: Tuya is the biggest privacy caution flag in the budget segment. Many cheap plugs are functionally indistinguishable but have inconsistent privacy practices. For tech-savvy users, flashing to ESPHome/Tasmota or using local integrations can help — but that requires time and risk. If you prefer to avoid tinkering, see our notes on buying strategies and checkout patterns to get the right SKU in the first place (checkout flows).

Amazon Smart Plug — Overall: 10/25

• Local control: 1 — Designed primarily for Alexa and Amazon cloud services.
• Default telemetry: 1 — Deep integration with Amazon services means telemetry for voice and device usage is expected.
• GDPR/CCPA posture: 4 — Amazon provides established mechanisms for data access and deletion.
• Clarity of docs: 3 — Policies are extensive but often broad in scope.
• Firmware transparency: 1 — Closed firmware; no alternative firmware paths supported.

Why this score: If you want the tightest Alexa integration and don’t mind Amazon cloud, this is simple. If privacy is your priority, avoid cloud-only smart plugs or isolate them on a separate network.

Ecosystem summary

• Best privacy out-of-the-box: Eve (HomeKit/Matter-first).
• Best for mixed users: TP-Link Matter models or Aqara hubs (if you use local Zigbee).
• Budget but private with work: Sonoff (flashable) or Tuya devices flashed to local firmware.
• Avoid for privacy-first setups: Generic Tuya OEMs and cloud-only Amazon/other vendor models unless network-isolated.

How to harden smart plugs and reduce telemetry (practical steps)

Whether you buy privacy-first hardware or have a cloud-heavy plug, these steps reduce exposure.

1. Choose local-first devices where possible. Prefer Matter-certified or HomeKit devices that explicitly support on-LAN control.
2. Segment your network. Put IoT devices on a VLAN or guest SSID; block access between that VLAN and your primary devices. This prevents lateral movement and limits what a compromised plug can reach — pair that approach with network monitoring guidance from field reviews on network observability.
3. Block telemetry at the network edge. Use a firewall or DNS blocker (Pi-hole, AdGuard Home) to restrict known telemetry domains; set up allowlists instead of blanket allow rules for devices you trust. For more on controlling edge traffic and hardening outbound paths, see our CDN and edge-hardening primer (how to harden CDN configurations).
4. Use a local hub. Home Assistant, HomeKit, or a Matter controller can broker automations locally and avoid cloud roundtrips for schedules and on/off commands. If you run an edge broker or message layer to keep automations resilient, the edge message broker field review is a good reference.
5. Disable optional cloud features. Turn off remote access, usage analytics, and voice assistant integration if you don’t need them; read the app settings carefully after initial setup.
6. Harden firmware and update processes. Apply vendor firmware updates promptly; for FLASH-capable devices, consider reputable community firmware (Tasmota, ESPHome) and keep it updated. For guidance on how to evaluate vendor telemetry and firmware trust, consult the trust scores for telemetry vendors review.
7. Use strong, unique credentials. Treat each vendor account like any other online account and enable 2FA where offered.
8. Monitor network traffic. Set up alerts for unusual outbound connections from IoT devices so you can act quickly if telemetry patterns change — and consider integrating edge/cloud telemetry tooling described in our edge+cloud telemetry piece if you manage many devices.

How to read a privacy policy fast: a 90-second checklist

• Does the policy list specific data categories (device IDs, telemetry, location, audio)? If it’s generic, that’s a red flag.
• Is there an accessible process for data subject requests (access, deletion, portability) and a specified response timeframe?
• Does the company clearly state retention periods or “how long we keep data”?
• Are third-party recipients named (analytics vendors, cloud providers) or are they described only as “partners”?
• Is there a dedicated privacy or security contact (DPO, email)? If not, expect friction when requesting deletion.
• Does the policy explain how to opt out of non-essential telemetry and analytics? For templated approaches to privacy docs, see a privacy policy template that illustrates clear data-category examples.

Firmware & update hardening: technical best practices

Firmwares are the software foundation of a smart plug. Treat firmware practices like the device's security diary.

• Verify signatures. Prefer vendors that cryptographically sign firmware. If firmware checks aren’t enforced on the device, updates can be riskier.
• Check changelogs. Vendors that publish detailed changelogs and CVE disclosures show better security hygiene.
• Use recovery plans. Before flashing community firmware, ensure you have serial access or a documented recovery method in case of failure.
• Preserve warranty tradeoffs. Understand that flashing aftermarket firmware often voids warranty and can complicate vendor support.

Two short case studies (experience-driven)

Case A — Easy privacy, minimal fuss

A midsize home used Eve Energy and a HomeKit setup. Automations for lighting and coffee were configured locally; remote access used HomeKit Secure Remote Access, which routes via Apple’s ecosystem but keeps automations processed on-device or on the local home hub. Outcome: near-zero telemetry exposure from plugs and predictable privacy posture.

Case B — Cheap plugs, big data until fixed

A renter bought a set of Tuya-based plugs to automate holiday lights. Out-of-the-box, the plugs sent frequent telemetry to the vendor cloud. The renter wanted privacy but not deep tinkering — they isolated the plugs on a guest VLAN and blocked several telemetry domains at the router. Later they swapped a few key outlets to Sonoff units flashed with Tasmota for full local control. Outcome: cost-managed privacy gains with incremental investments. If you need help picking a recommended SKU or want one-click buying advice, consider our live scorecard and purchasing notes alongside checkout best-practices at checkout flows.

Regulatory and market trends to watch (2026–2027)

• Matter maturity: Expect more vendors to ship Matter-first models in 2026–2027. Matter brings a real chance for default local control — but only if vendors don’t wrap Matter in cloud-only onboarding.
• Stronger enforcement: GDPR investigations and state-level CCPA/CPRA enforcement actions in 2025 signaled that vendors with obfuscated telemetry practices face penalties. Transparent privacy docs are now table stakes — see the recent consumer rights updates.
• Privacy-by-default demand: Consumers increasingly favor devices that advertise minimal telemetry as a feature. Expect new brands to market privacy as a primary differentiator; engineering teams should consider privacy-first microservices like a privacy-preserving microservice approach when designing data flows.
• Consolidation & OEM risks: Many budget plugs originate from the same OEM platforms (Tuya). Consolidation will keep prices low but uniform telemetry practices may remain unless buyers push back.

Interpreting a vendor score: what it means for you

Use the scorecard like a map, not gospel. A lower score doesn’t necessarily mean “unsafe” — rather, it signals more work (or tradeoffs) to get to an acceptable privacy posture. Choose based on your priorities:

• Minimal fuss privacy: Buy Eve or Matter-certified models and pair them locally.
• Budget + willing to tinker: Sonoff or older Tuya devices flashed to community firmware can be excellent value.
• Alexa/Google integration priority: Expect cloud telemetry; isolate devices on a VLAN and accept tradeoffs.

Quick checklist before you buy a smart plug

• Is the SKU Matter-certified or HomeKit compatible?
• Does the vendor explicitly state local control without cloud for core features?
• Can you opt-out of telemetry in the app during setup?
• Are firmware updates signed and described in release notes?
• Is the privacy policy readable and specific about data categories and retention?

Final recommendations

In 2026, privacy-friendly smart plugs are a realistic option for most buyers — especially if you prioritize Matter/HomeKit or are comfortable with lightweight network hardening. If you value minimal hands-on maintenance, buy a privacy-first vendor (Eve or Matter-certified TP-Link). If you’re price sensitive and technically confident, Sonoff or community-flashed Tuya devices can deliver local-only operation for a fraction of the cost.

Above all, remember: default settings matter. Even vendors with good privacy practices can expose data if you accept all analytics and remote-access options on setup. Spend five minutes with the app and your router firewall to dramatically reduce telemetry.
