For a financial-services CMO, AI makes it possible to turn a marketing idea into a working application in hours. Getting that application approved for use is often the harder part.
Can it access client data? Could the output expose MNPI? Who needs to review before it goes live? These questions determine whether a promising experiment becomes something your team can use, and those answers depend on what you're building.
A campaign planner using public information needs a different level of scrutiny from an investor portal handling confidential records. This guide helps you understand that difference and explains how Lovable protects its platform and helps secure the applications built on it, how to assess your use case, and what your team should consider before publishing.
How Lovable approaches security
Lovable addresses security at two levels: the platform your team builds on and the applications your team creates.
Platform security protects the building environment and gives your organization control over access. It includes measures such as encryption, isolation between workspaces, enterprise identity controls, audit logging, and PII detection, prevention, and scrubbing. These help your security team assess Lovable as a vendor and govern its use.
Application security helps identify risks in what you build. Lovable provides checks for issues such as unsafe database permissions, exposed credentials, vulnerable dependencies, and application-code vulnerabilities. Security findings give builders and technical teams a basis for reviewing and improving an application before release.
Assess the risk of your application first
Before building, these are a few questions that can help you assess the risk of your project:
- Data: Will it use public information, internal material, personal data, or confidential investment information?
- Audience: Is it for your team, external partners, or clients?
- Actions: Does it display information, change records, send communications, or make recommendations?
- Consequences: What happens if its output is incorrect or someone gains unintended access?
- Oversight: Who owns the application, reviews it, and can take it offline?
These questions establish a practical risk profile and the examples below are starting points for internal assessment, rather than formal regulatory classifications.
| Risk profile | Examples | What to consider |
|---|---|---|
| Lower risk | • Internal campaign planner using synthetic data • Event-page prototype • Tool for organizing already-approved public content |
Keep data limited, control sharing, review outputs, and check app security before publication |
| Higher risk | • Investor portal • Personalized fund-marketing experience • Application connected to CRM records • Tool using unpublished valuations or deal information |
• Define who can access each record and perform each action • Limit connected data, enforce permissions in the backend, and test those boundaries with different users |
"Internal" also does not automatically mean lower risk: an internal application containing material nonpublic information may require extensive controls.
These examples describe risk, not permission to provide a particular category of data to Lovable. Before connecting client records, check the data against your agreement. Section 3.8 of Lovable's Business and Enterprise DPA prohibits providing sensitive data, including financial account numbers, government identifiers, biometric data, and protected health information. Access controls and EU inference do not override those restrictions. Data Processing Agreement
What changes when you build a higher-risk application?
Use your answers above to decide what the app should allow, after confirming that the data is permitted under your agreement. For permitted internal or confidential information, be specific about who can see it. If it changes records or sends messages, define who can take those actions.
Describe these requirements when you prompt Lovable, then test that they work. Here are a few examples.
| If your application… | Build and check for… |
|---|---|
| Contains internal or confidential information | Require sign-in and restrict access to the intended audience. Check access to the published app separately. These are separate controls to those which define who can access your project editor. |
| Shows different information to different people | Define exactly who can see each record. Enforce permissions in the backend or database, not just by hiding buttons or pages. Ask Lovable to test this for you through prompting. Ask it to confirm unique users cannot retrieve each other's information. |
| Connects to a CRM, database, or another business system | Limit the connection to the data and actions the app needs. Check whose credentials it uses and whether app users could gain access beyond their own permissions. |
| Changes records or sends communications | Separate viewing from editing and sending. Add a review-and-confirm step for consequential actions, and enforce who can perform them. |
| Displays financial figures or approved marketing content | Use a controlled source, show when information was updated, and keep calculations and required disclosures consistent. If AI generates text, prevent it from inventing missing figures or presenting drafts as approved content. |
| Uses AI with permitted internal or confidential information | First confirm that your agreement permits the information to be provided to Lovable, then decide what actually needs to reach the model. Check the applicable training policy, processing location, and connected providers. Configure EU inference where appropriate, while assessing storage and other tools separately. |
Connect your tools without opening up the wrong data
Connectors let you use tools such as your CRM, spreadsheets, and document library in Lovable. There are a few types of connectors to get comfortable with:
| Connection type | What it does | Who can see the data |
|---|---|---|
| Chat connector | Gives Lovable context while you build, for example a brief from your Google Drive account. It is personal to you and is NOT a connection in the published app. | Only you can use this connection. Information brought into a shared project may be visible to collaborators. |
| App + chat connector | Uses one shared account while you build and in your finished app, for example reading a spreadsheet for context and then posting an update to Slack as part of app functionality. | App users can see the data and use the actions your app allows, through the shared account's permissions. |
| App user connector | Connectors that use each person's own account, for example an app that visualizes sales performance but only shows each rep data related to their accounts. | Different viewers will see different data, depending on their access. |
| Custom connectors / MCP | You can create custom connectors and MCPs if our catalog isn't broad enough. | Depends on if you connect a chat or app connector. |
These are connection types, not separate lists of tools: a tool may support more than one connection type.
For app + chat connectors, you choose which teammates can use the connection to build apps. Separately, you choose who can view each published app in its publishing settings. More about App + chat connectors.
Example of how to use these controls: a dashboard for five people on your marketing team
- Restrict the audience: In Publish, open the audience setting. On Business and Enterprise, choose Custom and add those people or their group. On Free and Pro, use Invite only. Publish the change. Giving the whole workspace access would be broader than this use case needs. Set your app's audience.
- Choose whose data it uses: If each person should see only their own CRM records, use an app user connector where supported. If all five should see the same approved report, a shared connection with access only to that report may fit.
- Decide whether to save the data: For a simple dashboard, request live data where practical. If the app copies records into its own database, the source system's permissions do not automatically follow. Define and test access to those saved records.
- Test both boundaries: Check that someone outside the five cannot open the dashboard, and that each invited person sees only the records intended for them.
Understand the data basics
Once you know what data your app needs, check how it will be handled.
Is our data used for training?
Business and Enterprise customer content, including prompts, attached files, code, project files, and generated outputs, is excluded from model training by default under your organization's agreement with Lovable.
On Free and Pro, data may be used for training unless you opt out.
Does Lovable support GDPR compliance?
Yes. Lovable supports GDPR requirements and includes a Data Processing Agreement on Business and Enterprise plans. The DPA sets out Lovable's obligations when processing personal data on your organization's behalf, including security measures, subprocessors, international transfers, and assistance with data protection rights.
How does EU inference differ from data residency?
EU inference controls where AI model requests are processed. Data residency concerns where data is stored.
On Enterprise, EU inference routes AI model requests made while building and through the built-in AI connector in published apps to designated EU endpoints. If no permitted endpoint can serve a request, it fails instead of being routed elsewhere. Provider boundaries vary, some features are unavailable, and certain agent tools still process data in the US.
The setting does not change where app data is stored. If you connect an AI provider directly, assess that connection separately. EU inference documentation
How does hosting work?
When you publish through Lovable, it hosts your app at a lovable.app address. Paid plans can connect a custom domain. Lovable Cloud provides a built-in backend for features such as a database, file storage, authentication, and server-side functions.
The frontend is delivered globally. Your Cloud project's region controls where its backend database and files are stored; check this separately from AI processing locations. You can also use a connected Supabase backend or deploy outside Lovable. Hosting documentation
What else should we check for data security?
Restrict access to private files and database records, and collect only the information the app needs. Define retention and deletion requirements, including for copies imported from connected tools.
For secret API keys and credentials, use Lovable's secure input and backend Secrets storage. Values stored there are encrypted and supplied to backend functions without being exposed in browser code. Keep private keys out of frontend code and downloadable content.
Keep a record of changes
Once an app uses real data, you need to know who changed its setup and when.
Enterprise audit logs record activity in the Lovable workspace, including changes to members, roles, settings, connections, and project publishing. Each event includes the actor, time, action, and affected resource. Owners and admins can filter and export logs from Workspace settings → Security → Audit logs.
Logs are retained for 13 weeks, roughly 90 days. Export them if you need a longer record. If you need to track actions inside your app, such as an investor downloading a document or a user approving a communication, define those events as part of the app. Workspace audit logs are not a complete archive of everything your app's users do. Read more about audit logs.
Build with your existing brand
The same approach applies to brand consistency: give the team a clear starting point.
Bring your brand guidelines, colors, fonts, logos, and example designs into the build. A reusable design system lets projects use the same components and styling rules. Enterprise teams can also connect an existing component library distributed as an npm package. Review the result against your guidelines. Using design systems.
On Business and Enterprise, you can also turn an approved project into a design template, for example a standard event landing page. New projects copy its design and structure, then become independent projects. Later template edits do not automatically update those copies. Using design templates.
Know what your plan includes
The controls above depend on your plan. For a marketing team, the main differences are:
- Pro: Custom domains, removal of Lovable branding, and design systems.
- Business: Adds SSO, role-based access, design templates, security oversight tools, and no model training on customer data by default.
- Enterprise: Adds audit logs, automated user provisioning through SCIM, scheduled security scans, and additional workspace controls. Commercial terms and included usage are agreed in your contract.
This is a summary of the features relevant here; the plan comparison lists the full inclusions.
Budget for both building and running the app. Chatting and building use credits, and backend, AI, and some connector usage can also consume credits after applicable allowances. Connected services may have their own charges. Check usage limits and alerts before opening an app to a larger audience. How credits and usage work.
Before you publish
With the audience, connections, hosting, and brand in place, check the finished app.
Lovable provides platform protections and app security checks. You decide what data to use, who can access it, and what the app should let them do. Before publishing:
- Start with approved data: Use synthetic data while building. Check what a connection can access before adding sensitive information.
- Check who can access what: Review access to the project, preview links, published app, and underlying data. Test with different accounts, including someone who should not have access.
- Review and test: Address security findings. Test the app's main features and check that users cannot take actions they do not have permission to perform.
- Check the content: Review figures, claims, and disclosures through your firm's usual process. If the app pulls in new data or generates new text, decide what needs another review and how outdated content will be removed.
- Keep a record: Save the version that was approved, the supporting information, who approved it, and where it was shared. Platform activity logs may not contain everything your firm needs to retain.
- Name an owner: Make someone responsible for updates, new security findings, and taking the app offline when it is no longer needed.
Use the publishing restrictions available in your workspace to control who can put the app live.
For your first project, choose something useful with a limited set of data and users. Build it, test those limits, and use what you learn before adding more sensitive data or giving more people access.
