Privacy Policy
Last updated: October 3, 2026
This Privacy Policy applies to Protsy, a service operated by Lumvin LLC, a limited liability company registered in the State of Wyoming, United States, with its registered address at 312 W 2nd St Unit #A8167, Casper, WY 82601. Protsy ("we", "us") helps Etsy sellers create and manage listings with AI assistance. This policy explains what data we collect, why, and what your rights are.
What we collect
Account data: your email address and password (stored as a hash by our authentication provider, Supabase).
Etsy store data: when you connect a store via Etsy OAuth, we store encrypted access tokens, your shop name and ID, and the listings, orders and shop statistics needed to operate the service. We only request the OAuth scopes the features require.
Content you provide: product photos, descriptions, prompts and templates you upload or write in the app.
How we use it
To run the product: drafting listings, generating photos, syncing your catalog and orders, and producing reports about your own shop.
Text you submit and listing context are sent to Anthropic (Claude API) to generate titles, descriptions and tags. Photos and prompts are sent to fal.ai to generate images. These providers process the data to return results; we do not sell your data to anyone.
Social media sharing (Pinterest)
You can optionally connect your own Pinterest business account to share your product listings as Pins. When you connect via Pinterest OAuth, we store an encrypted access token and your Pinterest username and account ID. We request only the scopes the feature needs: reading your boards (so you can choose where to pin), creating a single Pin, reading a Pin's status, and reading your basic account info.
We publish a Pin only to your own account, only after you review and approve the content. The app never posts automatically or on behalf of other users. For each shared listing we keep a record of the Pin (its ID, the board, the caption and status) so you can see what was shared. We do not read or collect any other Pinterest data, and we do not sell or share this data.
Disconnecting Pinterest deletes its stored token. Our use of Pinterest data complies with the Pinterest Developer Guidelines and Terms.
Social media sharing (Instagram & Facebook)
You can optionally connect your own Meta (Facebook) account to share your product listings to a Facebook Page and a linked Instagram Business/Creator account. When you connect via Facebook Login, we store an encrypted access token and the identifiers of the Page and Instagram account you select (Page ID and name, Instagram account ID and username). We request only the scopes the feature needs: managing posts on the Pages you own and publishing content to your linked Instagram account.
We publish a post only to your own Page or Instagram account, only after you review and approve the content. The app never posts automatically or on behalf of other users. For each shared listing we keep a record of the post (its ID, the network, the caption and status). The image we publish is fetched by Meta from a public URL of your product photo. We do not read or collect any other Facebook or Instagram data, and we do not sell or share this data.
Disconnecting Meta deletes its stored token. Our use of Facebook and Instagram data complies with the Meta Platform Terms and Developer Policies.
Video sharing (YouTube)
You can optionally connect your own YouTube channel to upload your product videos. When you connect via Google sign-in, we store an encrypted access token and your channel ID and name. We request only the scopes the feature needs: uploading a video to your channel, and reading your basic channel info (so we can show which channel is connected).
We upload a video only to your own channel, only after you review and approve the title and description. The app never uploads automatically or on behalf of other users. The video file is fetched from a public URL of your product video. For each upload we keep a record (its video ID, title/description and status). We do not read, collect or modify any other YouTube data.
Disconnecting YouTube in Settings → Connections deletes its stored tokens immediately.
Traffic analytics (Google Analytics)
You can optionally connect your own Google Analytics 4 property so Protsy can report on your shop's traffic. When you connect with Google we store an encrypted access token and refresh token, and the ID of the property you select. We request one read-only scope (analytics.readonly): it lets us list the properties you have access to, so you can pick one, and read aggregated reports for the property you picked.
We only read. Protsy never creates, edits or deletes anything in Google Analytics, and this scope gives us access to no other Google product. The reports we read are aggregate metrics for your own property — sessions, users, page views, traffic sources, countries and top pages. We show them back to you and send them to our AI provider only to write the summary you asked for. Google offers no narrower read scope limited to a single property or metric.
Disconnecting Google Analytics in Settings → Connections deletes the stored tokens immediately.
File import (Google Drive)
You can optionally import product photos, videos and design files from your own Google Drive. We use the drive.file scope, the narrowest scope Google offers for this: it grants access only to the individual files you select yourself in Google's own file picker, and to nothing else in your Drive. Protsy cannot list, search or open a file you have not picked.
For each file you pick we download it once and copy it either into your Protsy media library, so it can be attached to a listing, or into your design library, so it can be printed on your products; we store an encrypted access token and the file's ID, name, type and size. We never write to, rename or delete anything in your Drive.
Disconnecting Google Drive in Settings → Connections deletes the stored tokens immediately. Copies already imported into your media library or design library stay until you delete them.
How we protect your data
In transit: all traffic to Protsy and to every API we call runs over HTTPS with TLS 1.2 or higher. At rest: our database and file storage are encrypted with AES-256 by Supabase, and every OAuth token — Google, Etsy, Shopify, Pinterest, Meta — is additionally encrypted at the field level with AES-256-GCM before it is written, with a key kept only in our server-side secret store and never exposed to the browser.
Access control: PostgreSQL row-level security restricts every query to the rows of the signed-in account, and the privileged service key exists only in server-side code and is never sent to the client. Administrative access to production systems is limited to authorised personnel, protected by two-factor authentication, and used only to operate and support the service.
Deletion and incidents: disconnecting an integration deletes its tokens immediately; deleting your account removes your data from active systems within 30 days, and from backups as those backups expire. If we become aware of a breach affecting your data, we will notify affected users and the relevant authorities without undue delay, and in any case within 72 hours of becoming aware.
Google user data: Limited Use
Protsy's use and transfer of information received from Google APIs to any other app adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Concretely: we use Google user data only to provide the user-facing features you connected it for — Analytics reporting, YouTube upload, Drive import. We do not sell it. We do not transfer it to third parties except to the service providers who process it on our behalf to deliver those features (our hosting and database providers, and the AI provider that writes the summary of your own Analytics report), to comply with applicable law, or as part of a merger or acquisition after notice to you. We do not use it for advertising or profiling, and we do not use it to train, fine-tune or otherwise develop generalised AI or machine-learning models.
No person at Protsy reads your Google user data except with your explicit consent, to resolve a support request you filed, for security purposes such as investigating abuse, or where required by law.
Secondary sales channel (Shopify)
You can optionally connect your own Shopify store to publish your listings there as products. When you connect via Shopify OAuth, we store an encrypted access token and your store domain. We request only the scopes the feature needs: creating and updating products, reading products, and reading and writing inventory levels and locations so stock quantities stay accurate.
We create or update a product only in your own store, only after you review and approve the listing. The app never publishes automatically or on behalf of other users. We do not access your Shopify customers, orders, or any other protected customer data — the integration is limited to product catalog and inventory management. For each product sent we keep a record (its Shopify product ID and status) so you can see what was pushed.
Disconnecting Shopify deletes its stored token. Our use of Shopify data complies with the Shopify API License and Terms of Use.
Where it lives
Data is stored in Supabase (PostgreSQL, hosted in the cloud) and the app is served by Vercel. Etsy, Shopify, Pinterest, Meta and Google/YouTube OAuth tokens are encrypted at rest with AES-256-GCM. Row-level security ensures each account can only read its own rows.
Third-party processors
Supabase (database, auth, storage) · Vercel (hosting) · Stripe (payments) · Anthropic (AI text generation) · fal.ai (AI image generation) · Etsy (store API) · Shopify (secondary sales channel API) · Google (Analytics reporting, YouTube upload, Drive file import — only for the integrations you connect). If you connect social platforms such as Pinterest, Meta (Facebook/Instagram), TikTok or YouTube for sharing, those integrations receive only the content you explicitly choose to share. Each processor receives only what is needed for its function.
Cookies
We use essential session cookies to keep you signed in, and minimal analytics cookies to understand feature usage. We do not use advertising or cross-site tracking cookies. See our Cookie Policy at /cookies for details.
Retention & deletion
Your data is kept while your account is active. Disconnecting a store deletes its tokens; deleting your account removes your stores, drafts, jobs and reports from our active systems within 30 days. You can delete your account directly in Account → Danger Zone, or submit a request at /data-deletion.
Your rights
Depending on where you live (GDPR, KVKK and similar laws), you can request access to, correction of, or deletion of your personal data, and you may object to or restrict certain processing. Email us at support@protsy.io and we will respond within 30 days.
