Yes, the Filtre app and Safari extension are completely safe to use. Your browsing data is never collected, and your filters and settings will never leave your device or iCloud account.
Filtre's development is directly funded and supported by its customers. The app is the product, not you or your data.
On iOS, Web Extensions like Filtre only work inside the Safari app. Most apps load websites within an 'embedded' version of Safari, and sadly it is not yet possible to run extensions there.
The fastest way to load the website with Filtre is to open the website in the Safari app. To do that, simply tap the compass button on the bottom right of the 'embedded' Safari. This will open the Safari app, and Filtre will immediately be active.
On macOS, Web Extensions can run inside Web Apps that were made with the 'Add to Dock' feature of Safari. For more info on how to set this up, see Can I use Filtre in Web Apps?
Filtre includes a built-in way to disable itself on specific websites. It's recommended to allow the Filtre extension to run on all websites, and then disable Filtre on specific websites through the Filtre menu in Safari. Rest assured, Filtre does not collect any of your data.
However, if you want, Filtre can also be allowed access on a per-website basis. There are three ways to run Filtre:
On macOS you can use Filtre in Web Apps that were created with the 'Add to Dock' feature of Safari. The Filtre exension is enabled by default. If it's not, you can enable it in the settings of the Web App (by pressing the command + comma keys inside the app).
Unfortunately this is not yet supported on iOS. This is a system limitation.
No, Filtre does not collect any of your data. Filtre needs access to the pages that you visit, in order to apply your filters and hide elements. However, none of this data is ever stored.
When you first enable Filtre, Safari will show an alert that informs you that extensions are able to access the pages that you visit. This is a default alert that is shown for all extensions, not just for Filtre.
You can find out more in Filtre's (short and simple) Privacy Policy.
If the keyboard shortcuts you've set up for Filtre are not working, it could be the case that they are also used by Safari, or the specific website that you're using. These keyboard shortcuts take priority over Filtre's keyboard shortcuts, preventing Filtre from picking up on them. To check if this may be the case, please try your keyboard shortcuts on a simple page without custom keyboard shortcuts (such as this one), to see if your keyboard shortcuts work there.
If you're using the StopTheMadness Safari extension, please note that if you have either the "Protect option-key shortcuts" or "Protect all key presses" options enabled, this will also block Filtre from reading your keyboard shortcuts. Disabling these settings will fix this.
If you're trying to enable the Filtre extension, and Filtre is not shown in the list of extensions, there are a few things you can check or try.
First, make sure the "Block All Cookies" setting in Safari is not enabled. You can re-enable it after you have enabled Filtre. Second, make sure the Filtre app does not require Face ID or Touch ID to open. Unfortunately, Safari will not show Filtre when this option is enabled.
Lastly, sometimes Safari isn't correctly detecting newly installed extensions. Restarting your device usually resolves this.
If after all of this Filtre still isn't listed, please reach out to me, and I'll look into it!
