Privacy notice

Data is stored in Google Firestore under your authenticated user scope when you use account-backed persistence features. This can include profile records, saved mortgage scenarios, saved comparisons, feedback reports, and signed-in affordability workspace data.

If you sign in, we set a secure HttpOnly session cookie to keep your account session active on protected pages. This cookie is used for authentication and route protection only and is cleared on sign out.

We also use Google Analytics, which may place analytics cookies or collect similar device and usage data to help us understand how the site is used, which pages are visited, and which journeys are working poorly or well.

Some settings and temporary state may also be stored locally in your browser for resilience and user experience fallback. This may include calculator layout or temporary UI preferences.

Retention baseline: saved profile data is retained until you request account-data deletion; active saved scenarios are retained until you delete them; archived scenarios are retained for up to 24 months and may then be automatically removed; feedback rate-limit records are operational controls and are not intended as long-term user content.

If you create a public mortgage comparison share, that share is intended to be viewable by anyone with the link. Shared comparison pages and generated reports should be treated as public-by-link content.

Do not include sensitive personal information in content you plan to share publicly. If you no longer want a shared comparison to remain available, remove or replace that share through the relevant signed-in workflow.

From profile settings, you can export your account data and request deletion of stored account-linked data.

Export provides your available account data in a portable JSON format. Deletion removes your stored profile and account-linked calculator data from the application data store, subject to operational constraints and any short-lived security records still required for abuse prevention.

NestBoost uses third-party infrastructure providers including Google Cloud, Firebase Authentication, Firestore, and Google Analytics. External market and rate-reference providers may also be used where relevant to calculator or guide content.

These providers operate their own infrastructure and operational policies. This notice describes how NestBoost uses those services in the context of the product.

Google Analytics helps us understand aggregate traffic and behaviour on the site. We do not use it to provide regulated financial advice or to make automated lending or eligibility decisions.

NestBoost provides planning tools, educational guides, and supporting product features. It is not a bank, lender, or regulated advice service.

This page is an operational privacy notice for product use and does not replace formal legal documentation where jurisdiction-specific wording is required.
