Privacy Policy

Last updated: June 18, 2026 · Applies to the SlopPatrol Chrome extension and this website.

Who we are

SlopPatrol is operated by SimplyDose LLC (Missouri, USA) under the registered name "SlopPatrol." Contact: support@sloppatrol.app. SlopPatrol is a Chrome extension that hides AI-generated pins on Pinterest.

1. Pinterest-label blocking — runs entirely on your device

SlopPatrol's first line of defense blocks pins that Pinterest itself has labeled as AI-generated. It does this by reading the labeling data Pinterest already sends to your browser (the gen_ai_topics and digital_media_source_type fields in Pinterest's own page data) and hiding, blurring, or badging the matching pins.

• This label-based detection runs 100% locally in your browser. It makes no requests to SlopPatrol servers for this step.
• We do not scrape Pinterest. The extension only reads data your own browser has already received as part of loading Pinterest.
• No generative AI is involved at any step.

A second layer — checking pins against community-confirmed verdicts — does contact our server. It's described honestly in section 3.

2. What we store on your device

The extension keeps a small amount of data in your browser's local storage (chrome.storage.local):

• An anonymous device ID — a random identifier (crypto.randomUUID) created on install, not linked to any name, email, or account.
• Your settings (on/off, display mode, whitelisted boards).
• Your local "pins hidden" counters.
• A list of pins you've personally flagged, so they stay hidden for you.

Your settings, counters, and self-flagged list stay on your device and are never sent to us. The anonymous device ID also lives on your device — it is sent to us only when the extension contacts the community database: when it checks the pins you view for community verdicts, and when you submit a flag (both in section 3). It is used only to apply per-device rate limits and to weight votes — never to identify you.

Uninstalling the extension deletes this local data, including the anonymous device ID.

3. Community protection — what the extension sends, and when

SlopPatrol's community protection means your browser talks to our database in two situations. In both, the data is anonymized and the pin images themselves never leave your browser.

3a. Checking the pins you view (automatic)

To hide pins the community has already confirmed as AI, the extension checks the pins you view. For each pin that Pinterest hasn't already labeled, it computes a one-way signature — a SHA-256 hash of the image's stable path — and sends those signatures, in batches (not one by one), to our server along with your anonymous device ID. The server replies only with whether each signature matches a community-confirmed AI pin. This check runs whenever the community feature is enabled; it is what lets the free tier hide pins other people have already confirmed.

Being straight with you about what this does and doesn't mean:

• We receive one-way signatures (hashes) of pins you view. A signature identifies a specific image — that's how a known AI pin is recognized — but the image cannot be reconstructed from it.
• The images themselves never leave your browser, and we send no pin URLs, search terms, board contents, names, emails, or accounts during this check.
• The signatures are tied only to your anonymous device ID, never to your identity. In principle that means our server can see that one anonymous device looked up a given set of image signatures; we use this only to return verdicts and to rate-limit abuse, and we never link it to who you are.

3b. Flagging a pin (only when you choose to)

If you click "Flag as AI" or "Mark as human" on a pin, you contribute that judgment to the community database so other users can be protected. This happens only when you act. A flag sends and stores:

In neither case do we ever send or store:

• The pin images themselves.
• Your name, email address, or any account profile.
• Your searches, your board contents, or your activity on any site other than the pins SlopPatrol checks or that you flag on Pinterest.

3c. Your IP address

Like any request to any website, these verdict checks and flags reveal your IP address to our server and to Supabase, the provider that hosts our backend (section 7). We use it only to deliver the response and to limit abuse. Our database does not store your IP address alongside your votes, and we never use it to build a profile of you. Supabase, like any web host, may process IP addresses transiently to route requests — see their privacy policy for details.

4. The community database

Our backend (hosted on Supabase) stores only anonymous, non-personal records. Verdict checks (section 3a) are read-only lookups; flags (section 3b) add or update the records below:

• Devices: the anonymous device ID and counters (votes cast, agreement rate, reputation, daily rate-limit counts).
• Images / verdicts: the image signature, pin URL, aggregate vote tallies, and the community/automated status of each flagged image.
• Votes: which anonymous device voted which way on which image.
• Aggregate counters ("pins caught by the Patrol," member counts) computed from the above.

Because the device ID is anonymous and never linked to your identity, these records cannot be tied back to you. Uninstalling removes your local device ID, so your browser can no longer be associated with past votes; existing anonymous vote records may remain in the community database.

5. Paid tier — Auto-Detect

The optional paid tier adds protection beyond Pinterest's own labels:

• On-device AI detection. A small detection model runs inside your browser. The images it analyzes are processed locally and are not sent to us or to any third party for this analysis.
• Extra community verdicts. Community-confirmed blocking (section 3a) is available to everyone; the paid tier additionally surfaces verdicts produced by automated detection. It uses the same anonymized signature check as section 3a — no additional data leaves your browser.

SlopPatrol uses no generative AI. "On-device, nothing leaves your browser" describes how this detection works.

6. Payments

If you subscribe to the paid tier, payments are handled by ExtensionPay (which uses Stripe to process cards). To issue and restore your license, ExtensionPay collects your email address at checkout. SlopPatrol does not see or store your card details. Your subscription email is used only for license validation and is not linked to your anonymous device ID or your flagging activity. See the ExtensionPay and Stripe privacy policies for how they handle payment data.

7. Service providers

We share data only with the providers needed to run the service:

• Supabase — hosts the community database and the server functions that receive flag submissions.
• ExtensionPay / Stripe — payment processing for paid subscriptions.

We do not sell, rent, or share your data with anyone else, and we never use it for advertising.

8. Permissions we request

• Access to pinterest.com — to read its labeling data and hide AI pins.
• Access to our backend (supabase.co) — so flag submissions can reach the community database.
• Storage — to remember your settings and counters locally.

On startup the extension may fetch a small configuration file (selectors and thresholds) so it keeps working when Pinterest changes its layout. This request sends no information about you.

9. What we never do

• No analytics, trackers, or ad SDKs — ever.
• No behavioral telemetry or browsing-history collection.
• No selling, renting, or sharing of your data for advertising.
• No generative AI anywhere in the product or this site.

10. Children

SlopPatrol is not directed to children under 13 and does not knowingly collect personal information from them.

11. Changes to this policy

We'll update this page if our practices change and revise the "Last updated" date above. Material changes will be noted in the extension's update notes.
