Words to know
Legal words from the lines above, in plain English.
- sell or share
- Under California law, selling means passing your data to others for money or other value; sharing means passing it on for targeted ads. For example, letting an ad network use your browsing history in return for ad space counts as a sale.
- personal data
- Any information that is about you or can be linked to you, from your name to your phone's ID. For example, your email, your IP address and the list of apps on your phone are all personal data.
- retention
- How long a company keeps your data before deleting it. For example, a policy might keep your messages for 30 days after you delete them, or for as long as it likes.
- opt out
- Something is on by default and stays on until you find the setting and turn it off. For example, your chats may be used for training unless you go into settings and switch it off.
- targeted advertising
- Ads chosen for you based on what you have done across other apps and websites, not just this one. For example, you look at shoes in one app and see shoe ads in a totally different app the next day.
- cookies
- Small files a website saves on your device so it can recognise you and remember what you did. For example, a cookie keeps you logged in and can also tell an ad company which sites you visited.
- tracking pixels
- Tiny invisible images or bits of code in a page, app or email that report back when and where you opened it. For example, a pixel in a marketing email tells the sender the moment you read it.
- consent
- Your clear agreement to something, given by an action like ticking a box or tapping Accept. For example, a pop-up asking if the app may use your location is asking for consent.
- worldwide license
- You let the company use your content anywhere on earth, usually for free and for as long as it likes. For example, a video you post can be shown in ads in any country without asking you again.
- indemnify
- You promise to pay the company's legal costs and losses if your use of the service gets it sued. For example, if you post a song you do not own and the label sues the app, you owe the app's lawyer bills.
- third parties
- Any company or person other than you and the app, such as advertisers, partners or analytics firms. For example, an analytics company that receives a record of every screen you tap is a third party.
- prompt
- What you type or say to an AI to get a response. For example, asking a chatbot to write a birthday message is a prompt, and it may be stored.

What does the app collect beyond what it needs to work?
They collect account data, prompts, uploads, device IDs, IP location, cookies, partner data, optional health and demographics, and Comet browsing history.
Does it record your voice, face or body, and what happens to that?
If you use voice features they process speech, and they list biometric identifiers for voice recognition. They do not say it is deleted when the session ends.
Are your chats and uploads used to train AI models, and is that off by default?
They say they use data to improve or create AI models. Email content is excluded, but there is no general training opt-out for chats.
Can employees or contractors read your conversations, and when?
Not stated in the documents.
Are you profiled or tracked for advertising?
They share data with advertising partners for measurement and interest-based ads, with cookie and app opt-outs.
Do they sell or share your data, and can you opt out?
They say they do not sell data for money, but they share identifiers and usage data with advertising partners and offer targeted-ad opt-outs.
What rights do they take over what you type and what the AI makes?
You keep ownership of your content, but you grant a royalty-free, transferable, sublicensable, irrevocable license while they store it, including to improve and promote the service.
How long do they keep your data after you delete it, and can you delete it in the app?
You ask them to delete personal data. They keep it as long as needed for the notice’s purposes or as law allows, and may keep some for legal or business reasons.
Does it build a lasting memory or profile of you, and can you see, edit or turn it off?
They save query history and preferences across sessions and tailor the service. Incognito stops saving search activity, but there is no full memory editor described.
Do they commit to basic security, and have they leaked data?
They say they use reasonable efforts to protect data but cannot guarantee security. No audit or bug-bounty program is described.
Is there a real age gate, and are teens protected?
You must be 13 or older. Teens need a parent to accept the terms. They do not describe age checks beyond self-declaration.
Will they tell you when the rules change, and is the policy specific?
Both documents are dated. Privacy says material changes generally do not apply to old data unless you consent. Terms say continued use after posting means you accept, with reasonable efforts to notify of material changes. Retention periods stay vague.
Can they close your account without warning, and can you get your data out first?
They may suspend or delete your account with or without notice, for any or no reason, and are not obligated to keep your content.
If something goes wrong, who pays?
The service is as-is, liability is capped at $100 or six months of fees, and you must indemnify them for claims tied to your content or use.
Do subscriptions renew on their own, and can you get a refund?
Subscriptions auto-renew at then-current rates. Payments are nonrefundable with no credits for unused time. Price changes take effect after reasonable notice.
If this app can act for you, does it warn you about scams?
May transact on unsafe websites on your behalf. Perplexity asks before a final order and does not say Comet refuses an unsafe site. This line is not from the privacy policy. We did not test the product. Mitigating prompt injection in Comet (2025)
