Privacy Policy

Last updated: 19 April 2026 · Applies to the Cachely Chrome extension and cachely.co.uk

      The short version: Cachely reads only your Gmail Promotions folder to find discount codes. We never read your personal emails, never store raw email content, and never sell your data. The extracted code, brand name, and expiry date are stored locally on your device only.
    

1. Who we are

Cachely is a Chrome browser extension that connects to your Gmail account to find discount codes and promotional offers in your Promotions inbox, 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 access only the Gmail Promotions label (the "Promotions" tab in Gmail). We never access your Primary, Social, Updates, Forums, or Spam 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 within promotional emails, Cachely sends the text content of promotional emails 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.

What this means in practice: The text of your promotional emails (e.g. "Here's your 20% off code: SAVE20, valid until 30 April") is transmitted to Anthropic's API, which returns the extracted code and expiry date. The raw email text is not retained by Anthropic after processing, in accordance with their API usage policy. No human at Anthropic reads your email content.

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 non-promotional content
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 data from emails outside the Promotions label

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 read your Promotions emails 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, no email content or personal data) is sent to Sentry.

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 of information received from Google APIs adheres 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.

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.
