Privacy policy
Effective 7 November 2026. Sillfern is published by Equal Information LLC. This page explains what the app does with information.
What stays on your device
Your rooms, plants, care history, notes and photos are stored only on your device. Sillfern has no accounts and no servers of its own, and it does not upload this content. Photos you add are copied into the app's private storage; the app never reads the rest of your photo library.
What Sillfern does not use
Sillfern never asks for your location. Day length is calculated from the latitude you choose yourself. It uses no analytics service of its own.
Reminders and the widget
Reminders are local notifications created on your device. The Home Screen widget reads a short plant summary that the app saves in a keychain item shared only between Sillfern and its own widget.
Advertising
Sillfern is free and shows ads served by Google AdMob. AdMob may collect device identifiers, advertising data, product interaction data and coarse location to choose and measure ads, and it may use them to personalise ads when you allow it. Where required by law you are shown a consent form (Google User Messaging Platform), and iOS asks whether the app may track you across other companies' apps and websites. You can answer either way, and you can change the answers later in iOS Settings and under Privacy options in the app where shown. Ads still appear if you decline, but they are less tailored. Google's practices are described at policies.google.com/technologies/partner-sites.
Subscription and rewarded videos
An optional monthly subscription removes ads. Purchases are handled by Apple; Sillfern receives only whether the subscription is active. You can also watch short rewarded videos to switch ads off for a while. The count of videos you watched is kept on your device.
Children
Sillfern is a general-audience gardening tool and is not directed to children under 13.
Your choices and deleting data
More, Delete all my plants and photos erases everything the app stores. Deleting the app removes the rest. Email us to ask any question about this policy.
Changes
If this policy changes we will update this page and its date.
