Frequently Asked Questions
Do I need to know how to code?
No. Ready-made Safari tools work without coding, and you can use built-in starter scripts or downloadable .1extnscript files. If you want to create or customize something, 1Extn includes an Ask ChatGPT option to help you get started. Writing JavaScript yourself is optional.
Can 1Extn replace other Safari extensions?
In many cases, yes. Many Safari extensions use JavaScript to change how webpages look or behave. A 1Extn script can provide similar webpage-based customization without another app. Some extensions depend on native features, accounts, network filtering, special permissions or other capabilities that webpage JavaScript cannot reproduce, so 1Extn cannot replace every extension.
Why use 1Extn instead of installing lots of small Safari extensions?
1Extn brings ready-made tools, scripts, searches, redirects and automation together in one app. For many webpage-based customizations, you can add or create the behavior you want without installing a separate Safari extension app for each small task.
What can I make with a 1Extn script?
A script can hide distractions, change a page’s appearance, add useful controls, simplify repetitive actions or customize a specific website. Start with a built-in script, download a ready-made .1extnscript from the Script Library, create your own, or use the Ask ChatGPT option for help.
Can I use scripts from other sources?
Yes. 1Extn supports plain JavaScript, compatible userscript-style code, bookmarklet code, and trusted HTTPS .js or .user.js links. Import and run only code you understand and trust.
Will scripts work on every website?
No. Websites change, some use custom components, and Safari or site security restrictions can limit what a script can access or change. Test a script manually on the intended site before relying on it.
What are scripts and Auto Run?
Scripts are personal webpage tools that can change how a site looks or works. Manual mode runs one at a time; Auto Run can run multiple trusted scripts automatically on the Safari sites you choose.
What happens if I don’t want scripts running automatically?
Use Manual mode. Auto Run is optional and remains off until you enable it for a trusted script and selected website. You can use scripts one at a time without enabling automation.
Does every feature work on iPhone, iPad and Mac?
Feature availability can differ by device. Features limited to iPhone and iPad are marked on this page, and the app shows the options available on your device.
Do I need Apple Intelligence?
No. 1Extn works with or without Apple Intelligence.
Does 1Extn collect my browsing data?
No. 1Extn does not collect or sell your personal data. Safari controls extension permissions. When you choose to send page information to a Shortcut, Scriptable workflow, search provider or another destination, that destination’s privacy terms and permissions apply. See the full privacy details.
