🔒 Short version: The browser extension stores your watchlist locally unless you sign in to sync it. It always sends price observations for products you track to our public price-history service; you can erase observations linked to your extension identifier. The website uses StatCounter for analytics. We are preparing to show Google AdSense ads on the website; when ads are enabled, Google and its partners may use cookies, IP addresses and similar technologies as described below. AdSense ads are not part of the browser extension or iPhone app. See Section 5 for privacy rights and Section 6 for third-party services and choices.
Price Drop Catch includes a browser extension, a website, and an iPhone/iPad app for tracking product prices. The extension stores your watchlist locally by default, but sends observations of products you track to our public price-history service as described in Section 4. Website visits and optional accounts involve additional data described below.
For extension price tracking, we do not ask for:
The extension stores your saved product information (title, price, URL, image), local price history, and alert preferences in your browser's local storage. Product observations and a random extension identifier are also sent to us as described in Section 4. If you sign in, your account watchlist and targets are stored on our server so they can sync across devices.
The extension also always contributes anonymous price data points to our public Public Price History feature — there is no on/off switch in settings. See that section for exactly what is sent and how to erase it.
Optional account. Creating an account is entirely optional — Price Drop Catch works fully without one. You may sign in with a one-time email link, Google, or Sign in with Apple. We store your email address to identify your account, send price alerts, and sync tracked products across your devices. If you use Google or Apple sign-in, we also store that provider’s stable account identifier so you can return to the same Price Drop Catch account; the provider supplies your email address for this purpose, which may be an Apple private relay address if you choose Hide My Email. We never receive or store your Google or Apple password, and we do not request access to Gmail, Google Drive, contacts, iCloud, or other provider data. You can delete your Price Drop Catch account and its associated login identities at any time. If you never sign in, no account or email is created.
iPhone and iPad app usage statistics. When you use the app while signed in, we collect your internal account ID, app version and build, operating system version, device category (iPhone/iPad), foreground activity, successful sign-in method (email, Google or Apple), and successful product-add requests from the app or share extension, and categorized request failures. The server also records the most recent connection IP address and its timestamp for troubleshooting; this replaces the previous IP and expires after 30 days. These reports do not include your email address, product URL, advertising ID, or precise location. We use them to understand app usage and improve the service, without cross-app advertising tracking or a third-party analytics SDK. Usage and error reports are best-effort, retained for up to 90 days, and removed when you delete your account.
We also process product-demand events such as add_product and remove_product with the product URL to understand which retailers are in demand. Website analytics and, once enabled, advertising involve third parties as described in Section 6.
Links pasted on this website. When you paste a product link into the “track a product link” box on pricedropcatch.com, we record the store’s domain, the link’s path with all query parameters removed, and whether we were able to read that page — for up to 180 days. This tells us which retailers to support next, and is stored without your IP address, account, or email attached to it.
If you are in the EU, EEA, or UK, see Section 5 for the legal basis we rely on to process this data and the rights available to you under GDPR / UK GDPR.
We use the product data you save to:
The extension uploads price observations for products you track regardless of account sign-in. Your account watchlist and target prices are sent to our server when you sign in to sync. We do not provide your account watchlist or email address to Google AdSense for ad targeting.
The extension stores its local watchlist and settings using the browser extension storage API (such as chrome.storage.local). Locally stored data is:
local, not sync storage)For anonymous price data collected under Public Price History (Section 4), see the retention policy described there.
Price Drop Catch includes a feature called Share anonymous price history. This feature is always on and cannot be disabled from the extension — it is core to how Price Drop Catch builds the public price-history charts at /p/ and helps other users' extensions cover a product when their own browser is closed. To keep this acceptable without an on/off switch, we've deliberately kept the data minimal and fully anonymous (see exactly what is and isn't collected below), and you can permanently erase everything you've contributed at any time — see Erase your data below.
Each time the extension successfully observes a new price for a product you have added to tracking, it sends a small payload to our server containing:
What we do not send or store:
The aggregated, anonymous data is displayed on public product pages (e.g. /p/<store>/<product>) so that any visitor can see the price history for a product. Data from multiple users tracking the same product is merged into a single history. We reserve the right to remove or anonymize individual data points that appear to be inaccurate, duplicated, or abusive.
Retention. Anonymous price data is retained for up to 24 months, after which it is automatically deleted.
Erase your data at any time. Open the extension settings and click the erase my data link under Data. This sends your randomly generated client identifier to /api/forget-client.php, which permanently deletes every price point uploaded from your installation and recomputes affected products' aggregates. You can also trigger the request manually by visiting https://www.pricedropcatch.com/api/forget-client.php?clientId=<your-id>; your identifier is stored under pdcClientId in the extension's local storage.
What erasure does and doesn't do. Erasing removes every price point already uploaded from your installation, immediately and permanently. Because this feature has no on/off switch, continuing to use the extension afterward will resume contributing new, anonymous price observations going forward — erasure clears your past footprint, it does not pause future collection. If you want future collection stopped as well, contact us ([email protected]) with your client identifier and we will honor that request; see Section 5.
If you are located in the European Union, the European Economic Area, or the United Kingdom, the General Data Protection Regulation (GDPR) and/or the UK GDPR give you specific rights over any personal data we process about you. This section explains those rights and how Price Drop Catch applies them in practice.
Who is the data controller? Price Drop Catch is built and operated by an independent developer, not a registered company. For the purposes of GDPR, the operator acting as data controller can be reached at [email protected] for any privacy question or rights request. We have not appointed a separate Data Protection Officer, as this is not required for an operation of our size and processing scope, but privacy requests are personally reviewed and actioned by the operator.
What personal data GDPR applies to here. Data that may reach us includes the product observations and random extension identifier described in Section 4, optional account and email-alert details, and the app usage data described in Section 1. Visiting the website also involves browser information processed by StatCounter and, once advertising is enabled, potentially Google and its advertising partners as described in Section 6. A random identifier or IP address may be personal data under applicable law even when it does not directly identify you by name.
Legal basis for processing (Art. 6 GDPR). We rely on the following legal bases:
add_product). This data is minimized, pseudonymous, never used to profile individuals or for advertising, and you can permanently erase it at any time — factors we weigh as outweighing our interest, and which we take into account further if you contact us to object (see below).Your rights. Subject to certain exceptions under applicable law, you have the right to:
https://www.pricedropcatch.com/api/forget-client.php?clientId=<your-id> directly. The request is processed immediately, not just queued.To exercise any of the above (other than self-service erasure), email [email protected] with your client identifier (found under pdcClientId in the extension's local storage) or the email address on file for alerts. We aim to respond within 30 days, as required by Art. 12(3) GDPR.
International data transfers. Our servers are hosted in the United States. Data you send to our service, including product observations and optional account information, may be processed there over encrypted HTTPS connections. Third parties named in Section 6 may process website-visit or advertising data in other countries under their own privacy practices and applicable transfer safeguards.
Retention. See Section 4 for the 24-month retention period on anonymous price data. Email addresses for alerts are kept only as long as the corresponding subscription is active and are deleted immediately if you unsubscribe or request erasure. Optional-account emails and associated login identities are deleted when you delete the account.
When checking prices, the extension makes direct HTTP requests to the retailer websites you have chosen to track (e.g., Amazon, Walmart, eBay). These requests are identical to a normal browser visit to that page.
The pricedropcatch.com website uses StatCounter (statcounter.com) to measure page visits. StatCounter receives the page URL and standard browser headers for visited pages; it does not receive your account watchlist.
Website advertising. We are preparing to use Google AdSense to display ads on selected website pages. At the date shown above, placing an ads.txt record does not itself load ads or set advertising cookies. When AdSense is enabled, Google and its advertising partners may receive the page URL, IP address, browser information and other identifiers, and may place or read cookies or use web beacons to deliver and measure ads, prevent fraud, and, where permitted by your choices, personalize ads. These third parties may process data under their own privacy policies. We do not send your Price Drop Catch account email, saved watchlist, or target prices to AdSense. Learn how Google uses information from sites that use its services and manage Google ad personalization in My Ad Center.
When you open a product link from the Price Drop Catch extension (popup, notification, or welcome flow) or from a product page on pricedropcatch.com, we may rewrite that link through an affiliate program before the retailer page loads. Programs we may use include Amazon Associates (non-US Amazon locales where we participate), Skimlinks, Impact, Rakuten, and similar retailer affiliate networks. If you later purchase, we may earn a commission at no extra cost to you. This helps fund the extension and the public price-history service.
Affiliate tags are applied only after you choose to open a product link. The extension does not inject affiliate codes or cookies into pages while you browse in the background. Product history pages on this website may also include affiliate links (e.g., via Skimlinks) that help support the service. Clicking a link may set a cookie on the retailer's site per their own privacy policy.
The retailer websites themselves may set cookies or log requests according to their own privacy policies, which are outside our control.
Cookies and choices. StatCounter loads by default unless you previously chose “Decline” in our website cookie notice. You can change that analytics choice using the cookie icon on the website or use StatCounter's opt-out page. This existing notice controls StatCounter only; it does not manage Google advertising consent. Before enabling personalized AdSense ads for visitors in the EEA, UK or Switzerland, we will use a Google-certified consent management platform to present the required choices. Your browser can also block third-party cookies, and Google ad preferences can be managed in My Ad Center. Affiliate-link cookies may be set by a retailer only after you choose to follow a product link and are governed by that retailer's policy.
The extension requests the following browser permissions:
None of these permissions are used to collect or transmit personal data.
Price Drop Catch is not directed at children under the age of 13 (or the equivalent minimum age in your jurisdiction, e.g. 16 in some EU member states unless local law sets it lower). We do not knowingly collect any information from children. If you believe a child has used this extension, please contact us and we will remove any associated anonymous data.
We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. We encourage you to review this policy periodically. Material changes that expand the data we collect will, where practical, be surfaced in the relevant product before taking effect.
If you have any questions about this Privacy Policy, want to exercise a GDPR / UK GDPR right described in Section 5, request deletion of anonymous data associated with your client identifier, or have any other concerns, please contact us at:
