Where did you get the font?

The same typeface can carry completely different rights depending on where the file came from. A face you use through Creative Cloud and the same face downloaded from Google Fonts are not the same licence, and the differences are the expensive part.

Google Fonts (SIL Open Font License 1.1)The font software may not be sold on its own, and a modified version may not keep the Reserved Font Name. Adobe Fonts (included with Creative Cloud)The two that catch people: you cannot hand the font files to a client or editor who needs to edit the file, and you cannot embed the fonts in an app or game. Both require a separate licence bought from the foundry. Creative Market (Commercial licence)The Commercial tier caps broadcast and streaming at 500,000 LIFETIME VIEWERS and end products at 5,000. A video that keeps growing can quietly pass the cap you bought. Apps and games are excluded entirely below the Extended tier. Envato Elements (subscription)The font is licensed to YOU alone: you may not hand it to a client, an editor, or a colleague in your own company. Installs are capped at two computers per seat, and YOU MUST UNINSTALL THE FONT WHEN YOUR SUBSCRIPTION ENDS. Work you already finished stays licensed forever; new work does not. Fonts bundled with Windows and OfficeEverything hinges on one clause repeated throughout: the permission applies UNLESS you used an application licensed for home, student or non-commercial use. Make it in Office Home & Student and the commercial permission does not apply. For video, captions must be rendered as an image and the font file must not be embedded in the video file.
