Everything you need to know about GridChat and Privacy Tier. Can't find what you're looking for? Contact us below.
Tap "Register" on the login screen. Choose any username (3–20 characters, letters/numbers/underscore only) and a password of at least 8 characters. No email required — GridChat uses Privacy Tier by design, so we don't need your identity.
Yes. Core messaging is completely free. PRO features (Privacy Mode, GhostMode, GP Vault, Safety Engine) are available for €25/month. Family (€69/month, up to 5 members) and Company plans (€50/month, up to 50 employees) are also available.
Go to the Chats tab → Find Contact → enter a username. If the person exists, you can add them as a contact. They'll receive a notification that you added them. They can accept or ignore it.
Tokens are earned through daily login and by inviting friends. Spend 1 token to send a message to a PRO user. Tokens reset monthly — stay active to keep earning. Free users can still message each other for free.
All chats between two users are automatically encrypted using Privacy Tier when both parties are PRO users. If your contact is on a free plan, messages use standard encryption. PRO users can enable Privacy Mode in the chat for additional protection.
Privacy Tier is GridChat's trademarked privacy system. It means your messages are encrypted end-to-end using the GP Encryption Engine — mathematically enforced, so not even Grid BV can read your messages. No backdoors. No exceptions. It's not a promise — it's mathematics.
No. Under Privacy Tier, not even Grid BV can decrypt your messages. Encryption happens on your device before anything is sent. Our servers only ever see encrypted ciphertext. The GP Encryption Engine uses AES-256-GCM, Curve25519, and double-ratchet forward secrecy.
GhostMode (PRO) makes you completely invisible. Other users cannot see your online status, last seen time, or typing indicators. You appear offline to everyone while still being able to read incoming messages. Toggle it on in Profile → GhostMode.
The Safety Engine is a 3-layer security system built into PRO: Phishing Shield blocks malicious URLs before you click them; Leak Monitor checks if your data appears in known data breaches; Contact Guard detects impersonators in your contact list.
GP Vault (PRO) is your private encrypted notes space. Store sensitive text, passwords, or personal data — all encrypted with your private key. Only you can decrypt and read it. Access it from the Vault tab in the main navigation.
Location sharing is optional and encrypted. When you share your location with a contact, it's encrypted end-to-end — we can't read it. Location sharing can be stopped at any time. PRO users also have access to Geofence Zones — you get notified when specific contacts enter or leave a geographic area you define.
Go to Profile → Upgrade to PRO. PRO costs €25/month. Billing is handled securely. Cancel anytime — your PRO features remain active until the end of your billing period.
Go to Profile → Delete Account. This permanently erases all your data in accordance with GDPR Article 17 — your messages, contacts, profile, and activity logs are all permanently deleted. This action cannot be undone.
No. All payments are processed by Stripe, a PCI-DSS compliant payment provider. We never see or store your payment card details. Your card data goes directly to Stripe over an encrypted connection.
Individual PRO subscriptions are not transferable. For family or company plans, the plan owner manages member access. Contact us at privacy@gridchat.app for special circumstances.
Company accounts are available at €50/month for up to 50 employees. The Company Admin can invite team members, manage access, and transfer admin rights. Go to Profile → Company Dashboard to get started. Contact us for enterprise pricing above 50 users.
The Family plan (€69/month) covers up to 5 family members with all PRO features. The plan owner can invite and remove family members. All members get full PRO access including GhostMode, Privacy Mode, GP Vault, and the Safety Engine.
As a Company Admin or Family plan owner, go to your Dashboard → Invite Member. Enter their username and they will be added to your plan. They'll receive access immediately.
They may have GhostMode enabled (PRO feature), which hides online status from everyone. This is their privacy choice and cannot be overridden — it's a core Privacy Tier feature.

Yes — your account is tied to your username, not a device. Sign in on any device with your username and password. Note: messages are encrypted per-device — your private key stays on each device. This maintains Privacy Tier even across devices.
