PromptLensPromptLens Privacy Policy
Short version: PromptLens is a free, ad-supported library of AI prompts. There is no sign-up and no photo upload. The only purchase is the optional PromptLens Pro subscription, paid through Google Play. We count anonymous prompt views and copies to show what's trending. Our ad partner, Google AdMob, uses your advertising ID and device data to show ads. We do not sell personal data. Questions or deletion requests: geekzoneprohelp@gmail.com.
1. Who we are
PromptLens ("the App", "we", "us") is developed by Faiz, an independent developer based in India. For the purposes of India's Digital Personal Data Protection Act, 2023 ("DPDP Act") we are the Data Fiduciary for personal data processed through the App. Our Terms of Use also apply.
2. Data we collect and why
| Data | Collected by | Why |
|---|---|---|
| Advertising ID, IP address (used to estimate approximate location), device and app information, ad interactions, diagnostics | Google AdMob (Google Mobile Ads SDK) | To show, measure and limit ads, including personalised ads where permitted, and to prevent ad fraud. |
| Prompt activity: which prompts are viewed, copied, opened in an AI app or shared, with a random install ID created by the App (not your advertising ID, name or phone number) | Us, via our own server (api.pl.thymi.tech) | To count views, show "trending" and view numbers, and decide which prompts to add. The install ID is stored only as a salted hash and is not linked to who you are. |
| Your email address and message, only if you email us (support, feedback or a content report) | Us | To reply to you, review reported prompts and handle your request. |
| Install and crash statistics that Google Play provides to developers in aggregated form | Google Play | To understand installs and fix problems. |
The App has no account. It downloads the prompt library and images from our server, which also receives the prompt activity above; IP addresses are used only transiently for security and rate limiting and are not stored with your activity.
3. Data that stays on your device
Your favourites, collections, "My Prompts", recently copied prompts, chosen options, language setting, reminder setting and the 24-hour premium unlock are stored only on your device. Search runs on your device. We cannot see this data.
4. What we do not collect
- No photos or videos. The App has no photo picker, camera access or upload. Sample images in the App are AI-generated examples made by us.
- No payment data. The App has no in-app purchases or subscriptions.
- No name, phone number, contacts, messages, precise location, microphone or files.
- We do not use any data to train AI models.
5. Ads and advertising ID
The App is free and paid for by ads from Google AdMob (app-open, native, banner, interstitial and optional rewarded ads). A rewarded ad that you choose to watch unlocks premium prompts for 24 hours on your device; it has no cash value. AdMob collects the data listed above to serve ads; this is the only case where data is shared with a third party for that party's own purposes. You can reset or delete your advertising ID, or opt out of personalised ads, in Android Settings → Google → Ads (wording varies by device). Where the law requires it, the App asks for your consent before personalised ads are shown. Learn more in How Google uses information from sites or apps that use its services.
6. Opening other AI apps
When you tap "Copy" or "Open in AI app", the prompt text is placed on your clipboard or handed by Android to the app you choose (for example Gemini or ChatGPT). We receive nothing back from those apps. Whatever you type, paste or upload there, including photos, is handled by that app under its own privacy policy and terms. Gemini and ChatGPT are trademarks of their respective owners; PromptLens is not affiliated with, endorsed by or sponsored by Google, OpenAI or any AI provider.
7. Notifications
If you allow notifications, the App shows one trend idea in the evening. The ideas are scheduled on your device; no notification server or push token is used and nothing is sent to us. They stop automatically if you do not open the App for a few weeks, and you can turn them off in the App's Profile screen or in Android settings.
8. Third-party services
- Google AdMob — Google Privacy Policy
- Google Play (app distribution, updates and Pro subscription payments; we never see your card details) — Google Privacy Policy
- RevenueCat (only if you buy or restore PromptLens Pro: processes a random app user ID, your Google Play purchase token, product and subscription status to manage the subscription; it does not receive your name or payment card) — RevenueCat Privacy Policy
- Our server for the prompt library and activity counts runs on a rented virtual server (VPS) operated for us.
Google may process data on servers in India or other countries, with safeguards provided by Google.
9. How long data is kept
- Prompt activity: per-install daily records are deleted after 2 days; only total counts per prompt (not linked to any install) are kept.
- Emails you send us: as long as needed to answer and keep a record, and no longer than 24 months.
- Ad data: kept by Google under its own retention rules.
- On-device data: until you delete it, clear the App's storage or uninstall the App.
10. Deleting your data
Uninstalling the App or clearing its storage (Android Settings → Apps → PromptLens → Storage → Clear data) deletes everything the App stored on your device and gives you a new install ID, so earlier activity can no longer be connected to you. To delete emails you sent us, write to geekzoneprohelp@gmail.com with the subject "Delete my PromptLens data"; we act within 30 days. To delete ad data, reset or delete your advertising ID in Android settings. More on the Delete your data page.
11. Your rights
Under the DPDP Act and other applicable laws you may ask for a summary of the personal data we process about you, ask us to correct or erase it, withdraw consent, have a grievance addressed by us and, if unresolved, complain to the Data Protection Board of India, and nominate another person to exercise your rights. Contact us using the details below.
12. Security
All data is sent over encrypted connections (HTTPS/TLS). Requests to our server are signed and rate limited, and install IDs are stored only as salted hashes. No method is perfectly secure, but we take reasonable measures to protect data.
13. Children
PromptLens is intended for users aged 18 and over and is not designed for the Google Play Families program. We do not knowingly process personal data of anyone under 18. If you believe a child has contacted us, tell us and we will delete the related data.
14. Changes to this policy
We may update this policy, for example if we add new features. We will change the "Last updated" date and, for significant changes, tell you in the App before they take effect.
