No account or password is needed. Your open draft is kept in this browser when storage is available. Saved properties are a separate shortlist.
Continue where you left off
- Return to this same website in the same browser profile and on the same device. Your draft reopens automatically.
- Choose Saved to open a property you saved earlier.
- After editing a saved property, choose Save property to update it. Draft changes do not automatically replace the saved version.
Working in several tabs
Each open tab keeps a separate draft. Refreshing that tab resumes its own draft. A new tab starts from your most recent draft. To recover another recent version, open Saved → Other recent drafts.
Saving different properties in separate tabs keeps both. If two tabs edit the same saved version, both edits are preserved as separate entries. Open each entry to compare them before choosing which to keep.
Automatic cleanup and draft recovery
Current saved properties and separate edits are kept. Older superseded saved revisions are cleaned up automatically; they are not a version history you can browse. If an old tab refers to a cleaned-up version, its draft stays available and Save as new keeps it as a separate property.
Other recent drafts keeps up to 12 inactive tab drafts for up to 30 days. Drafts in open tabs are protected. Your most recent draft and saved shortlist are not subject to that expiry. Close tabs running an older release before relying on automatic cleanup. Browsers without safe cross-tab coordination keep older recovery copies. Export a session for long-term backup.
Move to another device or keep a backup
Choose Export session to download a JSON file containing the current draft, saved properties, refinance inputs, stress settings, notes and checklist. Keep this file somewhere you can find again.
On another device, open Saved → Import session and select the file. You can restore the draft or just add the saved properties. Existing saved properties are kept. This is how you move your work between browsers or website addresses; there is no account sync.
CSV exports are useful for reviewing or sharing numbers. To resume editing later, export a session file.
Brave, ad blockers and private browsing
The calculator has no advertising scripts or third-party trackers. Ordinary ad blocking should not affect the maths or downloads. Saving uses this website’s local browser storage, not a tracking cookie.
Blocking all site storage can prevent saving. If that happens, the calculator keeps your work in memory while this page stays open and shows a message to export your session. Refreshing or closing the page can then lose that work.
Private or incognito browsing normally clears stored data when its private session ends. Brave’s “Forget me when I close this site” and other clear-on-exit settings can do the same. A successful save cannot tell us whether your browser will erase it later. Export important work before leaving.
If an extension blocks the calculator’s own JavaScript, calculations cannot run. Review permissions for this site individually; you do not need to disable protection for other sites.
What is in a shared link?
A link contains a copy of the inputs at the moment you share it. Property names, refinance figures, stress settings and the open tool are included. Address and tax details are optional; notes and checklists are excluded. Anyone who can access the site and has the complete link can read the included figures. Sharing does not create a live connection or account backup.
Remove a property or erase local data
Choose Saved → Remove from shortlist to remove one saved version. The Undo button is available for 30 seconds in Saved and in the notification after closing Saved. When the period ends, its old revisions and linked drafts are cleared while the page is open, or on your next visit. Unsaved changes and edits made during Undo stay in a separate draft. Independent saved copies and concurrent edits also stay separate.
To clear all calculator data for this website in this browser profile, open Saved → Manage local calculator data and choose Erase local calculator data. Export important property sessions and the separate purchase budget before confirming. Current-version calculator tabs reset; close older-version tabs first. This preserves your analytics choice and unrelated browser data. Downloaded backups, clipboard contents, browser history and shared links held elsewhere still exist.
If cleanup is blocked, the site reports that stored copies may remain. Retry after closing other tabs, or use your browser’s controls to clear this website’s data.
Lost saved properties
Check that you are using the same browser profile and website address. If site data was deleted, import your exported session file. We cannot recover deleted browser storage.
