built a Chrome extension that bulk deletes Facebook posts — without ever asking for your password
Most Facebook cleanup tools have one thing in common: they ask for your login credentials or want OAuth access before they'll do anything.
I get why. It's the easiest path to automation. But for anyone who's privacy-conscious, handing over account access to a third-party app is a non-starter. I was one of those people.
So I built around it.
The problem I kept running into
A few years back, I wanted to clean up an old Facebook account — years of posts, likes, comments I no longer stood behind. I went looking for a tool. The ones I found either:
Asked me to log in through their own portal (no thanks)
Required me to grant OAuth permissions (still no)
Made me export my entire Facebook archive and process it offline (slow, clunky, and didn't actually delete anything)
The manual approach? I did the math. Deleting 800 items one by one, with Facebook's confirmation dialogs, would take somewhere north of four hours. On a good day.
I didn't build anything that week. But I didn't forget the problem.
The constraint that became the product
The insight that unlocked everything was simple: the Facebook session is already open in the user's browser. I don't need their password. I don't need their credentials. The extension can operate through the live session — the same one they use to scroll their feed — and do everything locally, on their machine.
No data leaves the browser. No server in the middle. No credential risk.
That constraint — never touch the password — became the core design principle of DeleteActivity. Every decision flows from it.
What I actually built
DeleteActivity is a Chrome and Edge extension that bulk deletes Facebook posts, comments, likes, and Messenger messages. It works like this:
You open Facebook normally in your browser
Click the extension icon
Set filters: date range, content type (posts / comments / likes / messages), or keywords
Preview the matched activity list
Hit start — it runs automatically from there
The two things I'm most proud of technically:
Smart rate limiting. The extension mimics natural human behavior, slowing down when needed to reduce the risk of Facebook flagging your account as a bot. It's not foolproof — no tool can guarantee zero risk — but it's meaningfully safer than naive automation.
Filter precision. You can target exactly what you want to remove. Delete every post from 2017 that mentions a specific keyword. Leave everything else untouched. This matters because most people don't want to nuke their entire history — they want to clean specific chapters of it.
After cleanup finishes, you can export the deleted activity log as CSV or JSON.
What worked and what didn't
What worked: SEO has been the biggest driver by far. "Bulk delete Facebook posts" and "delete Facebook activity log" have real search volume, and ranking for them doesn't require going viral. I underestimated this early on and focused too much on social. Once I put effort into the landing page and supporting content, organic traffic picked up meaningfully.
What didn't: Posting in Facebook-related subreddits. The subreddits that cover Facebook tend to attract people frustrated with Facebook, not people looking for tools to clean it up. The intent doesn't match. Most of my Reddit attempts flopped.
Still figuring out: Paid conversion. The free tier (30 deletions/day) converts to paid more slowly than I expected. I'm currently testing whether removing friction from the upgrade flow helps, or whether the free limit just needs to be structured differently.
Where it sits today
DeleteActivity is live on Chrome and Edge. The free tier covers basic use cases. Paid plans remove the daily deletion limit — monthly or annual (50% off).
I've also built out a small product family in the same space: DeleteThreads for Meta Threads, DeleteTik for TikTok, and a few others. The core insight — local execution, no credential sharing — translates across platforms.
What I'm still trying to work out
A few things I'd genuinely love input on from this community:
Pricing structure: Is 30 deletions/day the right free tier? Too generous? Too restrictive? I've gone back and forth on this.
Distribution: What's actually worked for you when promoting a privacy-focused browser extension? Feels like the audience is real but hard to find.
Trust signals: Privacy tools have a credibility problem — users are skeptical by default (understandably). Beyond "runs locally," what actually moves the needle for you when deciding to install something like this?
If you want to try it: deleteactivity.com — works on Chrome and Edge, free to start.
Happy to answer any questions about the extension architecture, the Manifest V3 migration, or how I'm thinking about the product family.
