Privacy Policy

Kydel (“we”, “us”, “our”) is a Canadian grocery price-comparison service that calculates your Net Effective Price (NEP) after cashback, loyalty points, and flyer discounts. We are subject to the Personal Information Protection and Electronic Documents Act (PIPEDA) and applicable provincial privacy legislation.

• Account information: Email address when you create an account.
• Location: Postal code you enter to identify nearby stores. We do not collect precise GPS coordinates.
• Card and loyalty selections: The credit card types and loyalty programs you choose. We store card slugs (e.g., “amex-cobalt”), not card numbers or financial account details.
• Shopping list: Product names you add to your in-app list.
• Usage data: Search queries and page views, used to improve search relevance. Not linked to your identity for anonymous sessions.
• Early access signup: If you sign up for early access updates, we collect your email and optionally your postal code and referral source.

• To calculate and display your personalised Net Effective Price.
• To remember your card and loyalty selections across sessions.
• To identify deals at stores near your postal code.
• To improve our search relevance and product matching (aggregate analytics only).
• To communicate service updates if you have an account.

We do not sell your personal information to third parties. We do not use your information for advertising profiling.

Your data is stored in Supabase (a Canadian and US-based cloud database provider). All data is encrypted in transit (TLS 1.2+) and at rest. Access to your account data is restricted by row-level security policies — only you can read or modify your own card and loyalty selections.

We use the following third-party services to operate Kydel. Each processes data only as needed for their stated function:

• Supabase Inc. — Database, authentication, and data storage. Your account data and selections are stored here with row-level security.
• Vercel Inc. — Web hosting and content delivery. Serves the app and processes incoming requests.
• PostHog Inc. — Anonymous product analytics. We use PostHog to understand which features are used and improve the app. PostHog may use cookies or local storage for session tracking. Analytics data is not linked to your identity for anonymous users.
• Sentry (Functional Software Inc.) — Error monitoring. When the app encounters a technical error, diagnostic information (not personal data) is sent to Sentry to help us fix bugs.
• Resend Inc.— Transactional email delivery. Used to send early-access signup confirmation emails and product updates. Account-related emails (such as password resets) are delivered through Supabase’s built-in email service.

We do not share personal information with grocery retailers, credit card issuers, or advertising networks.

For server-side data processing (such as extracting deal information from flyer documents), we may use AI services from providers including Anthropic and Google. These services process flyer content only — they do not receive your personal information.

Some product images are sourced from Open Food Facts, used under the Open Database License (ODbL). Other product images are generated using AI tools for illustration purposes and may not represent exact product appearance or packaging.

We retain your account information and selections until you delete your account. Anonymous usage data is retained for up to 12 months for analytics purposes and then permanently deleted.

Under PIPEDA you have the right to:

• Access the personal information we hold about you.
• Correct inaccurate information.
• Delete your account and all associated personal data.
• Withdraw consent at any time (this may limit your ability to use personalised features).

To exercise any of these rights, email privacy@kydel.ca with the subject line “Data Request” and include the email address associated with your account. We will verify your identity and respond within 30 calendar days. If we need more time, we will notify you of the extension and the reason.

If you are not satisfied with our response, you have the right to file a complaint with the Office of the Privacy Commissioner of Canada.

Kydel uses browser localStorage to persist your card selections, loyalty programs, shopping list, and preferences between visits.

For product analytics, we use PostHog, which may set its own cookies or use local storage to track anonymous usage sessions. This data helps us understand how the app is used and improve features. Analytics data is not linked to your personal identity for users who have not created an account.

We do not use third-party advertising cookies or tracking pixels. We do not participate in ad networks or sell data to advertisers.

Kydel is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with their information, please contact us at privacy@kydel.ca.

We may update this Privacy Policy to reflect changes in our practices or applicable law. We will notify registered users of material changes by email and will update the effective date at the top of this page.

If we make material changes, we will ask you to review and re-accept the updated policy before continuing to use the app.
