Review What Your Phone Keyboard Learns
Check which phone keyboards are active, review what personalization saves, and understand what Full Access allows on iPhone.
A phone keyboard follows you from a casual message to a private note, a search box, or a form. Along the way, it can suggest words or offer shortcuts that make typing easier. A privacy review starts with identifying the keyboard you actually use. Then you can decide which conveniences are worth keeping and which information you would prefer the keyboard to forget.
Identify the keyboard you use
On an iPhone, open Settings and go to General, Keyboard, and Keyboards to review the available keyboards. While typing, touch and hold the emoji or switch-keyboard key to see your choices. A list with several languages may simply reflect the layouts you use. Pay attention to which entries are separate keyboard apps and which one you select for everyday typing.

On Android, start with the settings for the keyboard that appears when you type. For example, Gboard has its own Privacy menu. Looking at the keyboard itself is useful when a phone came with one keyboard and you later installed another. Reviewing the old keyboard's options tells you little about the one you use now.

Check whether a custom keyboard needs network access
Apple gives custom iPhone keyboards a restricted environment that denies network access by default. A keyboard that supports open access can use the network when you grant it “Allow Full Access”. Apple explains that this capability can let the keyboard send keystrokes for server-side processing. The keyboard developer's documentation is where to look for the features that use it and how they handle input. Apple's custom keyboard documentation
If you use a custom keyboard for one feature, check whether that feature needs full access. Try leaving the access off and testing the feature with ordinary sample text. If the feature requires it, you can decide whether to use the feature or switch keyboards. Review this separately from the settings of the app where you type, since that app handles the text you submit to it.
Read the learning controls separately
Gboard on Android illustrates why it helps to read each switch. Google describes “Personalize for you” as using audio recordings and transcripts saved on the device to adapt the keyboard. “Improve for everyone” is a separate choice. Google describes one of its improvement methods, federated learning, as keeping your typed or spoken text on the device for that process and sending what the model learned to Google to combine with updates from others. Check the documentation for the particular feature you are reviewing. Google's explanation of Gboard learning
Decide whether you want to adjust future learning, clear what the keyboard has saved, or do both. Gboard's “Delete learned words & data” option under Privacy clears its saved on-device learning data. If you are looking for a message or note that you typed earlier, use the controls in the app that holds it. Before you clear learned data, consider whether you rely on the keyboard to suggest specialized vocabulary or words you frequently type. Google's guide to deleting Gboard learning data
Look at shortcuts you saved on purpose
Some suggestions come from entries you created yourself. On an iPhone, Text Replacement under Settings, General, and Keyboard shows phrases you set up to expand from shortcuts. Apple also describes using iCloud to keep the personal dictionary up to date across devices. If you set up a shortcut years ago, review whether the phrase still belongs there and whether it is useful on the devices where you use that dictionary. Apple's text replacement guide
Pick a feature to test before making changes. For example, if you type in two languages, try a short sentence in each. It is easier to tell what changed when you adjust one setting and test it in a plain note with harmless sample text. Confirm that the right keyboard is active, then try the language, layout, or shortcut you care about. When you install another keyboard or set up a new phone, revisit the settings for the keyboard you select there.
