From time to time, we are obligated to remove fonts from Typekit; we refer to this as “retiring” the font. Font retirement may happen for a variety of reasons, but is typically at the request of the foundry, when a typeface is no longer available for licensing and distribution.
The majority of font retirements are because the font family has been updated with significant changes that necessitate replacing it with an entirely new family. For example, Alverata PE from TypeTogether was overhauled, retired, and replaced by the family Alverata.
Typekit continues to serve the fonts to any published kits, so existing websites will not be affected when fonts are retired. However, retired fonts are not available to use in new kits, and if you remove the font from an existing kit, you cannot add it again.
Thirty days before the font is retired, we’ll put a notice on the font family page on typekit.com with the retirement date and any other details, such as the name of a replacement font family.
If you have a font synced that is scheduled to be retired, we’ll also email you seven days prior to retirement to warn you of the upcoming change. After we retire the font, it will no longer appear in the Fonts tab of the Creative Cloud desktop application or in your desktop application font menus. It will also be automatically removed from the list of synced fonts in your Typekit account.
If there is no updated version of the font on Typekit that suits your needs and could be substituted, you would need to see if the foundry has the fonts available for purchase from their own website or through a reseller.
Any fonts you have purchased from the Typekit Marketplace will remain on your account for both web and sync use.
