Is Base44 safe for business data?

"Is it safe?" is really four questions when the thing you're building is an internal tool:

1. The platform. Is Base44 itself run securely? This is the vendor's job, and certifications are the evidence.
2. Your app. Does the tool you built show each person only what they should see? This is your job. Base44 provides the controls; it can't know your org chart.
3. The data. Should this kind of data be in a third-party app builder at all? This one belongs to you and whoever owns compliance in your company.
4. The people. Who has access today, and who still has it after they leave? Also yours.

Base44 makes a reasonable case on the first question. Most of the risk for an operator-built tool sits in the other three, and Base44's own docs say so plainly: "You are responsible for your app's security settings."

Everything in this section comes from Base44's own security page, docs, terms and certificate, checked 2026-10-16. We have not audited Base44 ourselves. Certifications tell you a third party has assessed the vendor's controls. They don't guarantee your particular app is configured well.

Certifications and legal

• SOC 2 Type II and ISO 27001, both listed on base44.com/security. The ISO certificate linked from that page is ISO/IEC 27001:2022, valid until 22 June 2028.
• The SOC 2 report itself is shared under a non-disclosure agreement. Base44's docs say to request it through the Base44 Trust Center ("Get Access"); the security page also has a "Request SOC Report" form.
• GDPR: the security page says Base44 is GDPR compliant, with a data processing agreement (DPA). The DPA is published at base44.com/dpa and describes itself as part of the Terms of Service, so we found no plan restriction on it.

Encryption

• In transit: TLS 1.2 or higher.
• At rest: AES-256, including backups, with secrets held in a cloud key management service.

That protects data moving over the network and stored on disk. It does nothing about a user who is logged in and allowed to see something they shouldn't, which is why the next section matters more.

Where your data is stored

• United States by default. Base44's docs add that account and billing details stay in the US whatever you choose.
• EU or UK storage is available on higher tiers, but Base44's pages disagree on which. The security page says "Elite and Enterprise". The docs say Business or Enterprise, with Elite only for workspaces created before October 1, 2026. The docs also say it applies only to apps created after April 16, 2026, and controls where data is stored, not where it is processed.

If your company has data residency obligations (EU customer data, for example), that's a plan decision. Get the answer for your plan from Base44 in writing.

Getting your app and data out

• Data: you can export a table as a CSV file from the app dashboard.
• Code: downloading a ZIP of the code or connecting to GitHub requires the Builder plan or higher.

Your app runs on Base44's hosting, database and login, so even with exported code, moving it elsewhere is a rebuild project, not a switch.

Built-in security scan

Every app has a security scan. Base44's docs say it is available on all plans, including the free plan, and checks for vulnerable dependencies, insecure code patterns, exposed secrets, missing login checks and weak data access rules. Code vulnerability scanning needs the Builder plan or above. Run it before you share any tool and treat it as a floor, not a sign-off: the docs say it "warns you about risks but doesn't stop you from publishing."

Base44's security overview puts it directly: "Base44 provides the tools, but always review your permissions and run a security scan before you publish." The tools are there on every plan. Whether they're switched on and set correctly is up to you.

Row-level security (who sees which records)

Row-level security is the rule that, for example, a sales rep sees only their own accounts while their manager sees the whole team's. In Base44 you set it per table: Dashboard, then Data, then the table's Permissions page, where you choose who can create, read, update and delete records. The Data page flags tables with permission risks. Test the rules by logging in as a low-access user and trying to view something you shouldn't.

Tenant isolation (more than one team or client)

If one app serves several teams, regions or outside clients, each group's data has to be walled off from the others. Base44's docs describe doing this with data permissions and row-level security, so people from one company can't see another's records. A common operator mistake is building for one team and then adding a second without revisiting the rules. If outside clients will log in, get a second person to test it before launch.

Logins, sharing and offboarding

• Decide who can open the app. Base44 lets you make an app public without a login; that's fine for a prototype and wrong for anything holding customer or staff data.
• Keep a named owner for every app. Tools built in an afternoon tend to outlive the person who built them.
• Remove leavers. Add the app to your offboarding checklist the same day it goes live.

What you upload in the first place

The safest data is data you never upload. Before importing a spreadsheet, delete the columns the tool doesn't need: personal phone numbers, salaries, ID numbers. A pipeline tracker rarely needs more than names, stages and amounts.

Health and payment card data

Base44's Terms of Service (section 4.3, last updated June 22, 2026) say "no sensitive data that is protected under special legislation and requires unique treatment (such as protected health information or credit, debit or other payment card data) will be shared with the Platform, other than if expressly agreed by the Company in prior writing and the appropriate agreement is in place." We found no HIPAA or business associate agreement (BAA) offer on Base44's public pages. Unless you have that written agreement, keep patient records and card data out.

Other regulated or contract-restricted data

Treat these as "ask first" categories. That means a written yes from whoever owns compliance or legal, not a thumbs-up in chat:

• Government ID numbers and similar identifiers
• Data covered by a customer contract that restricts where it can be stored or processed
• EU or UK personal data, if your plan stores it in the US only
• Anything confidential, if your plan allows Base44 to use it for AI training

Most of this isn't specific to Base44. It applies to any hosted app builder. Base44's certifications make it a stronger candidate than an uncertified tool, but no certification turns a red-line data type into a safe one.

Copy this into your build notes. Every item should be done before the tool is shared beyond you.

• I've written down what data the tool will hold, and removed every column it doesn't need.
• None of it is health, payment card or another red-line category, or I have written approval.
• I know where the data is stored (US by default) and that's acceptable for this data.
• I know whether my plan lets Base44 use our data for AI training (every plan except Enterprise), and that's acceptable.
• App visibility is restricted to the people who need it.
• Table permissions (row-level security) are set, and I've tested them by logging in as a low-access user.
• If more than one team or client uses the app, each group's data is isolated and tested.
• I've run Base44's security scan and fixed what it found.
• The app has a named owner, and someone else knows how it works.
• The app is on our offboarding checklist.
• If IT or security asks, I can point them to Base44's security page, Trust Center and DPA.
• I know my plan's integration credits: published apps use them, and credit-using actions pause when they run out until the monthly reset.

Base44 bundles hosting, a database and login, so your app and its data live on its platform. Our tracker also lists built-in hosting for Lovable, Replit, Bolt.new and v0. If you're choosing between tools on data handling, the side-by-side pages cover hosting and data for each pair: Lovable vs Base44, Base44 vs Replit and Base44 vs Bolt.new.

Is Base44 safe for business data?

For most internal business data, yes, if you set it up properly. Base44 states SOC 2 Type II and ISO 27001 certification and encrypts data in transit (TLS 1.2+) and at rest (AES-256). Who can see which records inside your app is something you configure, and Base44's own docs say you are responsible for your app's security settings.

Is Base44 legit?

Yes. Base44 is a commercial app builder with a free plan and paid plans, owned by Wix since its 2025 acquisition. Its security page lists SOC 2 Type II, ISO 27001 and GDPR compliance. We rate it 5/5 for non-coder ease in our review.

Where does Base44 store my data?

In the US by default. Base44's docs say Business and Enterprise workspaces can store app data in EU or UK clusters instead (Elite too for workspaces created before October 1, 2026). Its security page names Elite and Enterprise, so confirm with Base44 for your plan. Account and billing data stays in the US either way.

Does Base44 train AI models on my data?

It can, unless you are on Enterprise. Base44's docs say Enterprise workspace data is not used to train AI models, while data on all other plans, including Business, can be. There is no opt-out setting on lower plans.

Can I put health or patient data in Base44?

Not by default. Base44's Terms of Service say protected health information and payment card data must not be shared with the platform unless Base44 has expressly agreed in writing beforehand and the appropriate agreement is in place. We found no HIPAA or BAA offer on Base44's public pages.

Is a Base44 app secure by default?

Not entirely. The platform-level protections apply to every app, but access rules inside your app are yours to set. Define table permissions (row-level security), check who can open the app, and run the built-in security scan before you share it. The scan warns about risks but does not stop you publishing.
