Privacy Policy

Last updated: 20 April 2026  ·  Applies to the Cachely Chrome extension and cachely.co.uk

1. Who we are

Cachely is a Chrome browser extension that connects to your Gmail account to find discount codes from the store you're checking out at, and surfaces them automatically when you reach a checkout page. We are based in the United Kingdom. For questions about this policy, contact us at support@cachely.co.uk.

2. What data we access

Cachely requests read-only access to your Gmail account using Google's OAuth 2.0. Specifically:

• We search your Gmail Promotions and Inbox labels, filtered strictly by the sender name of the store you are currently checking out at. We never access Social, Updates, Forums, Spam, or Sent folders.
• We request the narrowest possible scope: gmail.readonly, which allows reading email content but no other actions.
• We never send, delete, modify, or forward any emails on your behalf.

3. What data we store

We store the minimum information necessary to provide the service. For each promotional email that contains a discount code, we extract and store only:

• Brand name — the sender's name (e.g. "ASOS")
• Discount code — the code itself (e.g. "SAVE20")
• Discount value — e.g. "20% off"
• Expiry date — if one is stated in the email
• Domain — the merchant's website domain

This data is stored locally on your device using Chrome's storage.local API. It is never uploaded to our servers or any third-party database. Raw email content — the subject line, body text, and any personal details — is never stored anywhere.

4. How we process your emails

To identify discount codes, Cachely sends the text content of emails from the relevant store to Anthropic's Claude API for processing. This is necessary because identifying codes, discount values, and expiry dates from varying email formats requires AI-powered parsing.

You are informed of this during the Cachely onboarding process and must acknowledge it before granting Gmail access. You can withdraw consent at any time by disconnecting your Gmail account within the extension.

5. What data we do not collect

• Personal emails, work emails, or any emails not from the store you're checking out at
• Your name, address, payment details, or any personally identifiable information
• Browsing history beyond detecting checkout page URLs
• Raw email content — this is processed and immediately discarded
• Any emails unrelated to the current store

6. Checkout page detection

Cachely's content script runs on all pages in order to detect when you reach a checkout page (based on URL patterns such as /checkout, /cart, /payment). No browsing data is recorded or transmitted. The detection happens locally on your device.

7. Third-party services

Cachely uses the following third-party services:

• Google Gmail API — to search your Gmail for emails from the store you're checking out at, with your explicit consent. Governed by Google's Privacy Policy.
• Anthropic Claude API — to extract discount codes from promotional email text. Governed by Anthropic's Privacy Policy.
• Sentry — for error monitoring. Only anonymised error data (stack traces, error messages) is sent to Sentry. No Gmail content, email text, promo codes, or any Google user data is ever included in error reports.

We do not use advertising networks, analytics platforms, or data brokers. Your data is never sold or shared with any third party for marketing purposes.

8. Google API Limited Use disclosure

Cachely's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements. Specifically:

• Gmail data is used only to provide the core Cachely feature — finding and applying discount codes on your behalf.
• Gmail data is not used for advertising, sold to third parties, or used to build user profiles.
• Gmail data is not transferred to other parties except as described in Section 7 (Anthropic API processing), which is necessary to provide the service and is the minimum required to operate it.
• Gmail data is never used for serving advertisements, including retargeting, personalised advertising, or interest-based advertising.
• Humans at Cachely do not read your Gmail data unless you explicitly share it with us for support purposes or we are required to do so by law.

9. Data retention and deletion

Extracted deal data is stored locally on your device and automatically expires after 24 hours, after which it is re-fetched if needed. You can delete all stored data at any time by clicking "Clear cache" in the Cachely extension popup, or by uninstalling the extension.

To revoke Cachely's access to your Gmail entirely, go to your Google Account permissions and remove Cachely from the list of connected apps.

10. Your rights

You have the right to:

• Withdraw Gmail access at any time via Google Account settings
• Delete all locally stored data by clearing the extension cache or uninstalling
• Request information about what data Cachely holds about you by contacting support@cachely.co.uk

As Cachely stores no data on our servers, there is no central database to erase — all data lives on your device and is under your control.

11. Children's privacy

Cachely is not directed at children under 13. We do not knowingly collect data from children.

12. Changes to this policy

If we make material changes to this policy, we will update the "Last updated" date at the top and notify users via the extension. Continued use of Cachely after changes constitutes acceptance of the updated policy.
