Before You Bounce: A Brutally Honest Checklist for Cleaning Up Your Data on Mainstream Platforms
Let's be real about something: deleting the app is not the same as deleting your data. If you've spent any meaningful time on mainstream social platforms — and most Americans have, across multiple accounts over multiple years — you've left behind a surprisingly rich trail. Photos with embedded location metadata. Every search you've ever typed into a platform's bar. A behavioral profile assembled from years of clicks, pauses, and scroll patterns that you never consciously handed over.
Moving to a decentralized alternative is absolutely worth doing. But doing it without a cleanup plan is like moving out of an apartment without taking your stuff. This guide walks you through exactly what to grab, what to delete, and what to understand about what stays behind regardless.
Why This Matters More Than You Think
Before we get into the how, let's spend a minute on the why — because it's easy to underestimate the scope of what these platforms actually hold.
Every major centralized social network maintains two distinct layers of data about you. The first is the obvious stuff: your posts, photos, follows, and profile information. The second — and more consequential — is the behavioral and inferred layer: what time of day you're most active, how long you hovered over a particular ad, what topics make you pause while scrolling, what your network's political leanings suggest about yours. This second layer is what powers targeted advertising, and it persists even if you delete every post you've ever made.
Under laws like GDPR in Europe, platforms are required to give you access to much of this data. The US doesn't have equivalent federal privacy law yet, but most major platforms have extended some download tools to American users anyway — partly due to public pressure, partly due to state-level legislation like California's CCPA.
The point is: you can see a lot of what they have on you. And you should, before you go.
Step One: Download Everything First
Before you delete a single thing, download your data archive from every platform you plan to leave. Deleting first means losing access to years of photos, messages, and content that you might actually want.
Facebook/Instagram (Meta): Go to Settings > Your Facebook Information > Download Your Information. Request a copy in JSON format if you want something machine-readable, or HTML if you just want to browse it. The archive includes posts, messages, photos, your ad interest categories, and — genuinely worth looking at — the "Off-Facebook Activity" section, which shows data Meta collected about you from third-party websites and apps.
X (formerly Twitter): Go to Settings > Your Account > Download an archive of your data. This takes a day or two to generate. The archive includes every tweet, DM, like, and your inferred interests and demographic data.
TikTok: Settings > Privacy > Personalization and Data > Download Your Data. TikTok's archive is notably less comprehensive than Meta's, but it includes your watch history, search history, and comment activity.
LinkedIn: Settings > Data Privacy > Get a copy of your data. LinkedIn lets you choose between a fast partial export and a slower comprehensive one — get the comprehensive version.
Google (if you use Google Photos, YouTube, etc.): Google Takeout at takeout.google.com lets you export data from virtually every Google product in one place. This one is worth doing even if you're not leaving Google entirely — it's a useful backup.
Step Two: Actually Read Your Ad Profile
This step is optional in the sense that it isn't required for cleanup — but it's deeply clarifying, and we'd argue it's essential for anyone who wants to understand what they're walking away from.
On Facebook, go to Settings > Ads > Ad Preferences. You'll see the interest categories Meta has assigned to you based on your behavior. They can be uncannily accurate, occasionally bizarre, and almost always more granular than you expected. Same exercise on Google: myaccount.google.com > Data & Privacy > My Ad Center.
Seeing this data concretely tends to be more motivating than any abstract privacy argument. It's one thing to know that platforms profile you. It's another to see that a corporation has correctly inferred your approximate income bracket, relationship status, political leanings, and health concerns from your scroll history.
Step Three: Revoke Third-Party App Access
This is the most commonly skipped step and one of the most important. Over the years, you've probably used your Facebook or Google login to authenticate dozens of third-party apps and services. Many of those apps still have active access to your account data — even if you haven't used them in years.
Facebook: Settings > Security and Login > Apps and Websites. Remove anything you don't actively use.
Google: myaccount.google.com > Security > Third-party apps with account access. Same drill.
Twitter/X: Settings > Security and Account Access > Apps and Sessions.
Revoking these connections doesn't necessarily delete the data those apps already collected — but it stops the ongoing feed and removes a potential security vulnerability.
Step Four: Delete or Deactivate Strategically
Now that you have your data and understand your footprint, it's decision time. A few things to know:
Deactivation vs. deletion: Most platforms offer both options. Deactivation typically hides your profile and content but preserves the underlying data. Deletion is more permanent — though most platforms have a 30-day grace period during which your data is recoverable. After that, deletion is generally final for your visible content, though behavioral and inferred data may persist in anonymized or aggregated form.
Stagger your deletions: If you're active on multiple platforms, don't nuke everything simultaneously. Give yourself time to migrate your social connections to decentralized alternatives before cutting off the old network.
Tell people where you're going: Post your Mastodon handle or your new Fediverse home before you close the door. The whole point is to maintain your community — just on better infrastructure.
Step Five: Handle the Stuff That Doesn't Delete
Here's the honest part: some of your data doesn't fully go away when you delete your account. Platforms maintain certain logs for legal compliance purposes. Data that's been shared with advertising partners has already left the building. Cached versions of your public posts may live in search engine indexes indefinitely.
You can submit removal requests to Google Search for specific URLs. You can opt out of data broker sites (a longer process, but tools like DeleteMe or Privacy Bee can help automate it for US users). But you should go into this process with realistic expectations: the goal is to minimize your ongoing exposure and reclaim what you can, not to achieve perfect erasure.
Your New Home Is Waiting
The platforms worth migrating to — Mastodon, Pixelfed, Calckey, PeerTube, and others in the Fediverse — don't build ad profiles on you. They don't have a financial incentive to keep you anxious and scrolling. Your data lives on servers run by communities, not corporations, and in many cases you can run your own.
But getting there cleanly matters. Take your photos. Reclaim your content. Understand what was built on your behavior. Then close the tab and don't look back.
