What do you mean by Rate Limiting?

• Inventory & map IDs: catalog all cookie/third-party IDs used and map them to first-party identifiers or Privacy-Sandbox tokens so you know what to minimize or stop sending.
• Server-side tokenization & translation: move ID resolution and consent checks to a server token service that stores ephemeral Sandbox tokens/hashed IDs and only issues the minimum token required for a purpose.
• Reduce payloads & aggregate on-device: change client flows to send only purpose-scoped, minimal signals (or use on-device aggregation/APIs) so measurement/ads receive no raw PII.
• Retention, consent propagation & testing: enforce short retention for Sandbox tokens, ensure consent flags map to token issuance/revocation, add E2E tests and fallbacks for non-supporting browsers, and log all actions for audit.

• Add a clear age declaration step where users state if they are under 18, and trigger a stricter flow only for teens
• For teens, collect parent/guardian consent with verified contact methods (OTP/email link) and store it in an immutable audit log.
• Gate high-risk features (data sharing, analytics, ads, KYC) behind purpose-specific consent and disable anything not allowed for minors.
• Provide simple withdrawal and deletion options that parents can control, and auto-expire teen consents when the user turns 18.

Consent Ledger Audit Report: Monthly log of all consents captured, withdrawn, expired, and version changes (timestamp + purpose + user ID).

Purpose-wise Consent Coverage Report: Shows % of users who have valid consent for each purpose (Aadhaar, UAN lookup, ESIC KYC, analytics, etc.).

Just-in-Time Notice Compliance Report: Tracks whether consent prompts were shown at the correct trigger points (e.g., UAN verification, KYC upload).

Data Access & Processing Report: Lists all modules/services that used personal data and verifies each access was tied to a valid, active consent.

• Catalog and Chart Tags/CMP: inventory and document every cookie/tag you are utilizing for consent, then update CMP to trigger more granular/intent-based signals and change tag firing from cookie checks to consent events. 
• Adopt Privacy-Sandbox APIs + server side: where measurement/ads exist, replace third-party cookie logic with Privacy-Sandbox APIs (Topics/FLEDGE/Attribution)  and move their aggregations/attributions to it and port aggregation/attribution logic into server-side, privacy-earning pipelines. 
• Leverage consent-mode + robust fallbacks: wire your consent signals to Consent Mode/CMP SDKs, so that your tags will honor your users choices; also provide for deterministic fallbacks (1st party cookies/hashes) for browsers that don’t support APIs. 
• Test, monitor, & update policy: test staged A/B’s, report API/measurement deltas, have rollback options, and update the privacy doc & user-choice UI as browser behavior & P.S policies change.

Use purpose-wise consent screens so employees separately approve use of Aadhaar, UAN, and ESIC data.

Ensure consent is explicit and fully logged with timestamp, purpose, version, and user identity in an immutable audit table.

Provide a simple withdrawal option that automatically updates all linked modules.

Show just-in-time consent notices during actions like UAN lookup or KYC upload.
