How To Delete Cookies On Android

Tips
1

I’m running out of storage and some sites keep showing old data or logging me in automatically. I’ve heard clearing cookies might fix this, but I’m confused by the different options in my browser settings (cache, site data, cookies, etc.). Can someone walk me through the exact steps to delete all cookies on Android, and explain what I should or shouldn’t wipe so I don’t break important logins or apps?

Short version. Clearing cookies helps with logins and stuck site data. Cache helps more with storage. You can clear both.

Here is how on Android for the main browsers.

CHROME

  1. Open Chrome.

  2. Tap the three dots top right.

  3. Tap History.

  4. Tap Clear browsing data.

  5. At the top pick Time range.
    • Last hour
    • Last 24 hours
    • Last 7 days
    • Last 4 weeks
    • All time

  6. To remove cookies and logins, tick:
    • Cookies and site data

  7. To free more space, tick:
    • Cached images and files

  8. Leave Browsing history off if you want to keep history.

  9. Tap Clear data.

  10. Close Chrome, reopen, log in again on sites you want.

FIREFOX

  1. Open Firefox.
  2. Tap the three dots.
  3. Tap Settings.
  4. Under Privacy and security tap Delete browsing data.
  5. Tick:
    • Cookies
    • Cached images and files
    • Uncheck Browsing history if you want to keep history.
  6. Tap Delete browsing data.
  7. Confirm.

SAMSUNG INTERNET

  1. Open Samsung Internet.
  2. Tap the three lines bottom right.
  3. Tap Settings.
  4. Tap Personal browsing data.
  5. Tap Delete browsing data.
  6. Tick:
    • Cookies and site data
    • Cached images and files
  7. Tap Delete data.

If you want less auto login in future

Most sites keep you logged in with cookies. If you clear cookies you log out. To stop them from logging you in again every time:

• When a site asks “Remember me” or “Stay signed in”, leave it unticked.
• In Chrome, go to Settings > Site settings > Cookies.
Turn off “Allow all cookies” and use “Block third party cookies”. This still keeps logins working but blocks a lot of tracking.
• Do not use “Block all cookies” unless you like sites breaking.

If storage is the main issue

Cookies use little space. Cache uses more. I checked my phone right now:

Chrome app info > Storage
• User data: 1.2 GB
• Cache: 850 MB

Most of that is cache, not cookies. So for more space, focus on clearing cache:

System way:

  1. Open Settings on Android.
  2. Tap Apps.
  3. Find Chrome or your browser.
  4. Tap Storage.
  5. Tap Clear cache.
    Do not tap Clear data unless you want to reset the app, lose all settings, logins, etc.

Auto clear on exit (for privacy)

Chrome for Android is limited, but Firefox helps more here.

Firefox:

  1. Settings.
  2. Delete browsing data on quit.
  3. Turn it on.
  4. Pick Cookies and Cached images and files.

Then every time you close Firefox from the tab switcher, it wipes those.

What each option means in your browser

• Cookies and site data
Login sessions, site preferences, items in shopping carts.
Good to clear if sites show old data, weird login issues, wrong accounts.

• Cached images and files
Copies of pictures and files the browser stores to load faster.
Safe to clear. Browser will reload them. Saves a lot of space.

• Site settings
Permissions like location, camera, notifications.
Clear if sites have messed up permissions.

If one site keeps showing old stuff

Instead of nuking everything:

Chrome:

  1. Go to the site.
  2. Tap the lock icon in the address bar.
  3. Tap Cookies or Site settings.
  4. Tap Clear and reset or Clear cookies.
  5. Reload the page and log in again.

That way you fix that one site and keep others intact.

So for your case

  1. To fix old data and forced logins
    Clear “Cookies and site data” and “Cached images and files” for at least “Last 7 days” in your main browser.

  2. To free storage
    Use app Settings > Storage > Clear cache for Chrome or whatever browser you use.
    Do this every few weeks if storage gets low.

Expect to re-enter passwords for some sites after this. That part is normal and means the cookie purge worked.

You’re on the right track, but I’d tweak what @vrijheidsvogel said in a couple places.

  1. About storage
    They’re right that cache is the real storage hog, not cookies. But if your browser’s “user data” is huge, that can also include site databases (IndexedDB, local storage), not just cookies. Those can get big with stuff like PWAs, offline web apps, or bloated news sites. Clearing only cache sometimes doesn’t touch those.

So if storage is really critical and you don’t mind re‑logging in, use the browser’s “Clear browsing data” and make sure cookies / site data is selected as well as cached images and files. That wipes:

  • Cookies (logins & prefs)
  • Local storage / IndexedDB (bigger offline chunks)
  • Cache (images, scripts, etc.)

That combo frees the most space from the browser itself.

  1. If you only want to fix 1 or 2 broken sites
    I’d actually start small instead of nuking all cookies:
  • Open the problem site.
  • Go into that site’s info (little lock icon or info icon near the address).
  • Clear that site’s cookies / data only.

This is underrated and often fixes:

  • Stale shopping carts
  • Stuck “logged in as wrong account”
  • Pages that keep loading an old version

You keep all other sites intact, so less password pain.

  1. Old data vs auto logins
    These are related but not identical:
  • Old data is often cached HTML / JS or local storage. Clearing cache and site data is what fixes that.
  • Auto login is almost always cookies and sometimes “remember me” checkboxes. To dial this back without constantly clearing cookies:
    • Stop checking “remember me” when logging in.
    • In Chrome, leave “Block all cookies” off (breaks too much), but do Block third‑party cookies like @vrijheidsvogel said.
    • Also turn off “Preload pages for faster browsing” in Chrome (Settings → Privacy and security). That can quietly log you back in or pre‑load stuff you didn’t ask for.
  1. What I’d actually do in your situation
    Since you mentioned both storage and wrong / old data:
  • First, go to your Android Settings → Apps → your browser → Storage → Clear cache.
    That’s the quick storage win and does not kill logins.
  • Then, inside the browser, run Clear browsing data for at least last 7 days with:
    • Cookies / site data
    • Cached images and files
      Leave browsing history unchecked if you care about it.

After that, expect:

  • A few sites will ask you to log in again.
  • Some pages might load slower once while they rebuild cache.
  • The “old data” / stuck login symptoms should be mostly gone.
  1. For next time so this doesn’t keep happening
  • Pick one main browser and stop using 3 different ones. Each one keeps its own cache and cookies, so you multiply the problem.
  • Once a month, clear that browser’s cache only.
  • Only clear cookies / site data when you have login weirdness or you really need the storage.

TL;DR:

  • For storage: clear app cache + browser cache.
  • For old data / forced logins: clear cookies & site data, ideally per‑site first, then global if needed.

Skip the full nuclear wipe for a second and think of this in “profiles” instead of just cookies vs cache.

1. Use separate browser profiles for “always logged in” vs “throwaway”

Instead of constantly clearing cookies:

  • Use your main browser for accounts you actually want to stay logged in on.
  • Install a second lightweight browser and use it for “one‑off” visits, random shops, news, etc.
    • When storage gets tight, you clear that browser’s cookies and cache aggressively without touching your main logins.

This usually cuts down both auto logins and bloat over time, because junk sites never get to sit in your “long term” browser.

2. Tweak cookie behavior, not only clear it

What @vrijheidsvogel and the other reply said about clearing is fine, but the part people skip is ongoing control:

  • Turn on “Clear cookies on exit” (or “Delete cookies and site data when you close” if your browser has it) only for the secondary browser.
  • For the main browser, leave that off, but:
    • Block third party cookies.
    • Use site‑specific rules:
      • Allow cookies for banking, email, socials.
      • Set others to “clear on exit” or “blocked.”

This keeps storage + tracking under control without you constantly visiting “Clear browsing data.”

3. Check download clutter, not just browser data

A lot of “storage from browsing” is not actually cookies or cache:

  • Go into your Downloads folder and clean out PDFs, images, APKs, etc from old visits.
  • Some sites save big offline files that show up as generic “Other” storage in Android, not as browser cache.

You may free more space there than in cookie settings.

4. Tradeoffs if you keep clearing cookies often

Pros:

  • Fixes broken logins and old site versions.
  • Reduces tracking and weird “remembered” behavior.
  • Can trim extra site databases along with cookies.

Cons:

  • You will re‑enter passwords constantly unless you use a password manager.
  • 2FA prompts show up more often.
  • Some sites nag you again with cookie banners and onboarding.

Compared to @vrijheidsvogel’s approach, I’d say: do not rely solely on periodic full wipes. Set up a system (two browsers + per‑site rules) so you rarely need the big “delete everything” button at all.
