Comprehensive Database Schema Optimization & Security Plan 1. Problem Statement & Root Cause Analysis A. Metric Accuracy & Role Tracking Issues Symptom: Admin dashboard counts are mismatched (e.g., showing 25 users in one place but 26 in another; 24 startups vs 22 actual startups). Root Cause: Role tracking is currently split between profiles.role and a separate user_roles table. The OverviewPage.tsx counts "Total Users" from profiles but counts "Startups/Partners" from user_roles. If a newly registered user (especially via Google OAuth) is inserted into profiles but has a mismatched or missing entry in user_roles, the counts skew. Goal: Unify role tracking to a single source of truth (profiles.role) and eliminate the redundant user_roles table entirely. B. Security Vulnerabilities (Supabase Linter Errors) Symptom: Database linter is throwing SECURITY DEFINER and RLS Disabled errors. Root Cause: partner_wallet_stats view joins directly with auth.users AND is marked SECURITY DEFINER, exposing sensitive authentication data globally. app_unified_revenue and live_datasets are also SECURITY DEFINER views which bypass RLS of the querying user. Several tables (app_ad_summaries, app_daily_ad_stats, app_dataset_summaries, domain_taxonomy) simply lack Row Level Security (RLS) entirely. Goal: Convert views to use SECURITY INVOKER or remove them, decouple from auth.users, and apply strict RLS policies to all remaining tables. C. Schema Redundancy & Dead Code Symptom: Bloated tables, confusing settings relationships, empty or unused LLM tracking tables. Root Cause: Settings are scattered: app_settings holds general preferences, while app_profiles holds app-level info, and enterprise_profiles holds partner info. They share redundant fields (like bank details, notifications). Ad stats are fragmented: app_daily_ad_stats and app_ad_summaries track clicks/impressions separately from the main app_daily_revenue_stats pipeline. Wise (TransferWise) is no longer being used as the payout provider, but wise_* fields pollute multiple tables. Outdated or empty LLM pipeline tables (dpo_triplets, interaction_pairs) from legacy features. Goal: Merge settings into role-specific profiles, aggregate stats accurately, and purge unused columns/tables to slim down the schema significantly. 2. Infrastructure & Database Changes (Phase 1) We will execute these changes via a new SQL migration file (e.g., 20260518_schema_optimization_and_rls.sql). 1. Drop Wise Integrations ALTER TABLE platform_settings DROP COLUMN wise_payment_links; ALTER TABLE payouts DROP COLUMN wise_transfer_id; ALTER TABLE enterprise_profiles DROP COLUMN wise_recipient_id; ALTER TABLE app_profiles DROP COLUMN wise_recipient_id; 2. Eliminate Unused/Redundant Tables DROP TABLE user_roles; (Migrating data to profiles.role first if needed) DROP TABLE app_settings; (Fields migrating to app_profiles and enterprise_profiles) DROP TABLE dpo_triplets CASCADE; (Unused LLM data) DROP TABLE interaction_pairs CASCADE; (Unused LLM data) DROP TABLE app_ad_summaries CASCADE; (Replaced by app_daily_revenue_stats) DROP TABLE app_daily_ad_stats CASCADE; 3. Consolidate Settings into Profiles Extend app_profiles to hold startup-specific notification defaults and bank details that were previously in app_settings. Extend enterprise_profiles to hold its respective financial/contact info if missing. 4. Refactor Security & Views Drop the app_unified_revenue view. We will query unified metrics directly from app_daily_revenue_stats via the frontend or a simple RPC function to prevent security bypass. Drop and recreate partner_wallet_stats to be SECURITY INVOKER. Replace the dependency on auth.users by joining billing_transactions, dataset_purchases, and campaigns explicitly against profiles. Recreate live_datasets as SECURITY INVOKER. Remove admin_platform_stats view entirely, or refactor it into an RPC to fetch active totals. 5. Apply 100% RLS Coverage ALTER TABLE app_dataset_summaries ENABLE ROW LEVEL SECURITY; + Policy ALTER TABLE domain_taxonomy ENABLE ROW LEVEL SECURITY; + Policy (Likely just a public read policy: FOR SELECT USING (true) ) 3. Application & Frontend Updates (Phase 2) We will make ZERO changes to the UI design/layout. All updates are scoped exclusively to the data layer, React Hooks, and Zustand Stores. A. Auth & Role Handling ( src/stores/auth-store.ts) Remove all references to the user_roles table. Overhaul fetchAppUser to solely check profiles.role to determine if a user is a startup, partner, or admin. Update setUserRole to only fire an UPDATE on profiles. B. Admin Dashboard Metrics ( src/pages/admin/OverviewPage.tsx&UsersPage.tsx) Action: Fix the metric inaccuracies (e.g., 25 vs 26 count bug). Change: Remove queries to user_roles. In OverviewPage.tsx, we will fetch the total count, startup count, and partner count natively from the profiles table via a single.select('role, id') call. Change: In UsersPage.tsx, map the user list from the profiles join cleanly. C. Startup Dashboard Settings ( src/stores/startup-store.ts) Change: Remove the fetchAppSettings and upsertAppSettings methods. Replace their functionality inside fetchAppProfile and upsertAppProfile. Settings queries that originally looked for discord_notify or currency will now pull directly from the consolidated app_profiles row. D. Revenue Graphs & Ad Stats ( src/lib/startup-revenue.ts) Action: Ensure the UI doesn't rely on dropped tables (app_ad_summaries or app_daily_ad_stats). Change: The fetchStartupRevenueSnapshot logic will be streamlined to pull purely from app_daily_revenue_stats and payouts, ensuring clicks, impressions, and revenue are strictly tied to our ledger-verified statistics rather than detached logs. E. Partner Enterprise Config ( src/lib/partner-enterprise.tsor related) Change: Remove attempts to read/write wise_recipient_id or query legacy partner_wallet_stats view with exposed auth dependencies. 4. Execution Strategy To ensure zero downtime or breaking changes in the browser, the execution will follow this precise order: Migration File Generation: Write the SQL to copy any straggling data (user_roles -> profiles.role, app_settings -> app_profiles), drop the tables, alter the views, and enable RLS. Frontend Wiring: Update the TypeScript interfaces, Zustand stores ( auth-store.ts, startup-store.ts), and helper utilities ( startup-revenue.ts) to match the new schema structure. Admin Panel Update: Overhaul the data-fetching queries in OverviewPage.tsx and UsersPage.tsx to restore 100% metric accuracy. Validation: Run TypeScript type-checking to ensure no broken imports or missing keys remain.

Current statement: “Monetize your startup without charging users” — but this overpromises since Zerocost currently provides supplemental revenue, not full monetization. The dilemma is balancing honesty (it’s just extra revenue today) with strong positioning (it still feels like monetization). Both are strong, but they signal slightly different things. “Turn your free users into revenue” - THIS IS BEST More powerful + punchy Feels like a core transformation Broader (doesn’t lock you into one method) Better as a headline “Monetize your free users (without paywalls)” More explicit Immediately explains how (no paywalls) Slightly more “SaaS/technical” tone Feels like a feature/value prop

We do not always need consent for ads. Under GDPR, consent is generally not required for non-personalized contextual ads that do not rely on personal data, profiling, or behavioral tracking. Since Zerocost focuses on privacy-first contextual advertising, many ad placements may operate under legitimate interest or outside consent requirements depending on implementation and jurisdiction. However, developers remain responsible for ensuring their own compliance based on how they use the product. To make this practical, Zerocost should support two consent models. First, developers can use the built-in Zerocost consent popup (triggered from the shield/privacy button), where users can manage permissions for products like data collection or recordings. Second, developers should be able to run their own custom consent flow, such as collecting consent during registration, onboarding, account creation, or inside their own privacy settings page. This should be controlled directly in the Zerocost dashboard with a clear Enable / Disable Consent Popup setting. If enabled, Zerocost handles the consent UI and stores consent states through the SDK. If disabled, the developer confirms they are managing consent independently and acknowledges that legal compliance obligations (GDPR, ePrivacy, CCPA, and other applicable laws) become their responsibility. Additionally, the dashboard should include API hooks or SDK methods so developers using custom consent flows can pass verified consent states into Zerocost. This gives startups flexibility while ensuring Zerocost can still respect user preferences technically. The result is a system that works for both privacy-conscious builders who want turnkey compliance tools and advanced teams who prefer to manage consent inside their own product experience. (We need a solid plan for all of this so before building make a plan). NOTE: We must also update our TOS, Privacy Policy, Docs. Legally, it can be permissible for Zerocost to let developers handle consent instead of Zerocost always handling it, if roles, responsibilities, and data flows are structured correctly. This is common in SaaS/SDK ecosystems. For example, many analytics, ad tech, CRM, and customer-support SDKs rely on the website/app operator to obtain consent. Why this can be valid Under laws like GDPR and the ePrivacy Directive: The app developer / website operator is usually the primary party interacting with the end user. They often act as the controller (or joint controller in some cases) for user data collected through third-party SDKs. A vendor like Zerocost can act as a processor for some services, or an independent/joint controller for others depending on product design. That means the app can collect consent in its own signup flow, cookie banner, onboarding, or privacy center, then pass the consent signal to Zerocost. But only if these conditions are met 1. Clear contractual allocation Your Terms, DPA, and dashboard settings should clearly state: If developer disables Zerocost consent UI, developer confirms they obtain valid consent where required. Developer must provide required notices. Developer must pass consent signals accurately. Zerocost may suspend products if no lawful basis exists. 2. Zerocost must technically honor consent If user has not consented (where needed), Zerocost should not collect/process that data. Example: Ads product (contextual only): maybe no consent needed in some regions/use cases. Product 2 datasets: likely higher risk, often consent strongly recommended. Product 3 recordings: explicit consent strongly advisable. 3. Granular consent by product User should be able to separately agree/refuse: Contextual ads Interaction data monetization Recordings / session capture 4. Audit trail Store timestamp, version of notice, region, consent state source (“developer-managed” vs “Zerocost popup”). Important risk area You cannot simply say “developer is responsible” and ignore everything. Regulators look at actual control and benefit, not only contracts. If Zerocost determines purposes/means of processing, you may still have obligations. Practical best model for Zerocost Use a hybrid system: Default Zerocost popup enabled (easy compliance path) Advanced mode Developer disables popup and uses custom consent manager. Require them to certify: lawful basis obtained where required notices updated consent revocable signals passed to Zerocost SDK SDK example zc.consent.sync({ ads: true, datasets: false, recordings: false, source: "developer_cmp" }) Strategic recommendation For trust + scale, market it as: “Bring your own consent manager, or use Zerocost’s built-in privacy controls.” That is stronger than forcing everyone into one popup.
