What this covers
NaturePhenomena keeps a small amount of information in your browser so the site can remember your garden, your preferences and whether you are signed in. This page lists every item we store, what it does and how long it stays. The same information is described in plain terms in our Privacy Policy; this page is the detailed inventory.
No advertising or tracking cookies
We do not use advertising cookies, social-media tracking pixels, analytics services or cross-site tracking. We do not sell or share information about how you use the site for advertising. Nothing here is used to build a profile about you outside NaturePhenomena.
The one cookie we set
A cookie is a small text file a site asks your browser to keep. NaturePhenomena sets a single cookie of its own, and it is strictly a display preference:
| Name | What it does | How long it stays |
|---|---|---|
| sidebar_state | Remembers whether the navigation drawer was last open or closed, so it opens the same way next time. | 7 days |
Your garden data (local storage)
Garden plans and preferences are saved in your browser's local storage rather than in cookies, because that is the right tool for information this large. It stays on your device and is not uploaded unless you sign in and sync a project to your account.
| Name | What it does | How long it stays |
|---|---|---|
| verdant-plan-v1 | Your garden projects: site details, sun and soil conditions, plant recommendations, saved visualizations and nursery or landscaper contacts. | Until you delete them or clear your browser data |
| np-projects-v1 | Your list of saved garden projects. When signed in, it is a copy of the projects saved to your account, so they also appear on your other devices. | Until you delete it or clear your browser data |
| np-projects-synced | When signed in: a short record of which project changes have already reached your account, so changes made offline or just before closing the page are sent on your next visit. | Until you delete your account or clear your browser data |
| np-active-project-scope | Which garden project you are currently working in. | Until you delete it or clear your browser data |
| np-course-progress-v1 | Which Design Course lessons you've marked complete. When signed in, this is a copy of the progress saved to your account, with a short record of what has already been sent. | Until you delete it or clear your browser data |
| np-course-completed-at-v1 | The date you completed each Design Course lesson, shown in your To-Dos. | Until you delete it or clear your browser data |
| np-forum-name | The display name you last used in the course discussion. | Until you delete it or clear your browser data |
| np-photo-id-cache-v1 | Plant names suggested for your last 20 identified photos (a fingerprint of each photo plus the suggested names — never the photo itself), so uploading the same photo again shows its result instantly. | Until you delete it or clear your browser data |
| np-units-v1 | Your measurement preference, metric or imperial. | Until you delete it or clear your browser data |
| np-shop-region | Whether the shop shows the Europe or USA store. | Until you delete it or clear your browser data |
| naturephenomena-projects-v1 | Your Academy progress: completed guides, tasks, levels and quiz results. When signed in, this is also saved to your account. | Until you delete it or clear your browser data |
| Sign-in session entry | Keeps you signed in and lets the site recognise your account. Created by our authentication service when you sign in. | Until you sign out, or until you close the browser if “Remember me” is off |
While a tab is open (session storage)
Session storage is cleared automatically when you close the tab. We use it only for sign-in behaviour.
| Name | What it does | How long it stays |
|---|---|---|
| verdant-remember | Records whether “Remember me” was ticked when you signed in. | Until you close the tab |
| verdant-session-live | Marks that this visit should keep your sign-in, so a password-reset link opened in a new tab still works. | Until you close the tab |
Cookies set by services we use
Some features load content from third parties, and those parties may set cookies of their own while you use that feature. We cannot control them and they are governed by their own policies, not ours.
| Name | What it does | How long it stays |
|---|---|---|
| Google Maps | When a map of nearby nurseries or landscapers is shown, Google sets its own cookies to display the map and prevent abuse. | Google's own retention; see Google's privacy & terms |
| Paddle (cdn.paddle.com) | The checkout window used for paid plans. Paddle sets cookies for payment security and fraud prevention while you check out. | Paddle's own retention; see Paddle's privacy notice |
| Cloudflare Turnstile | A security check shown only after repeated failed sign-in attempts. Cloudflare processes your IP address and browser signals to tell people from bots. It isn't loaded otherwise. | Cloudflare's own retention; see Cloudflare's privacy policy |
Maps and checkout are the only places third-party cookies appear, and both load on request: a map is only fetched when you open the nurseries or landscapers view, and Paddle only loads when you start a checkout.
How to control them
You can clear or block these at any time from your browser's privacy or site-settings controls. Clearing site data removes your saved garden projects, photos and preferences from that device, and signs you out — so export or download anything you want to keep first. Blocking cookies entirely will not stop you from browsing the site, but sign-in, saved projects, maps and checkout will not work.
You can also delete your saved garden from this browser directly on the Privacy Policy page, and delete your whole account from Account & purchases.
Changes
If we add a service that sets cookies, or change what we store, we will update this page and move the date above. Material changes are announced to subscribers.
