Lovable
High riskAI app builder that turns natural-language prompts into full-stack web applications, typically deployed on Supabase backends, aimed at founders and non-specialist builders.
Is Lovable safe for confidential data?
Lovable has documented, recent security failures on both sides of its product. On the platform side, a Broken Object Level Authorization flaw in its API let any account read other users' source code, AI chat histories, and database credentials; reported in March 2026, it was patched only for projects created after November 2025, leaving older projects exposed for roughly 48 days while the company initially called the behavior intentional. On the output side, earlier scanning (CVE-2025-48757) found 170 Lovable-built apps with 303 endpoints leaking personal and payment data because generated Supabase row-level security was missing or wrong. Customers do own the code they generate under Lovable's terms, but for a professional firm the platform is currently hard to justify for anything involving confidential data without an independent security review of both the account and everything it has shipped.
Risk by plan
The same product often carries very different terms depending on the tier — consumer plans are where the exposure concentrates.
Public projects; no organizational agreement. The account tier most exposed in the 2026 API incident and the one shadow adopters use.
Private projects and higher limits; data-use specifics are not clearly published per tier — obtain them in writing.
Data handling
Training on inputs
Lovable's published materials do not clearly document whether prompts and project content are used for model training across plans — confirm in the current privacy policy and any negotiated terms before adopting.
Retention
Projects, chat histories, and connected credentials persist in Lovable's cloud; the 2026 API flaw showed that this retained data (including database credentials embedded in projects) was reachable across accounts for older projects.
Residency
Stockholm-based vendor operating on cloud infrastructure; specific processing regions are not clearly published. EU establishment helps GDPR posture but does not answer PIPEDA or Quebec Law 25 residency questions for Canadian firms — ask.

Frequently asked questions
Did Lovable have a security breach?
Yes — two distinct incidents. In April 2026, coverage confirmed a BOLA flaw in Lovable's API that let an ordinary account pull other users' source code, AI chat histories, and database credentials; the fix initially applied only to projects created after November 2025, and older projects stayed exposed about 48 days after the March 3 HackerOne report, with Lovable at first denying a breach. Separately, CVE-2025-48757 documented 170 Lovable-generated apps whose missing Supabase row-level security exposed 303 endpoints leaking names, payment data, and API keys.
Does Lovable own my code?
No — under Lovable's product terms the customer owns the applications and code they generate, and you can export the code to your own repository. Ownership is the wrong worry; the practical issues are that your source, prompts, and connected credentials live in Lovable's cloud, and that generated apps ship with security defaults you are responsible for auditing before real user data touches them.
Someone on the team already built an internal tool on a free Lovable account. What now?
Treat it as an unreviewed exposure, not a convenience. Free-tier projects sit outside any company agreement, predate no security review, and — per the 2026 incidents — may have had code, chats, and credentials reachable by others. Rotate every credential the project ever touched, review its row-level security before it holds real data, and move sanctioned use onto a paid, contracted footing with monitoring for the next spontaneous build.
