epolar Terms of Use

1. Features and free access

epolar offers photography, photo import, filters, composition tools, film frames and handwritten signatures. Taking and saving photos with the White and Matte Black frames is free. Importing photos, adjusting their color or composition, and saving individual photos or batches with free frames do not require registration, sign-in or Pro. Importing does not use up shots in your film pack. Saving creates a new photo without overwriting the imported original.

epolar Pro includes the currently available frames marked as Pro, as well as creating, editing and applying signatures. Without active Pro access, you can still use free features and view or delete signatures already stored on your device. To save an unsaved edit that uses a Pro frame or signature, you need valid access. Alternatively, remove the signature and choose a free frame. Your originals and previously saved photos are unaffected.

Film packs, Burst, Live Photos, audio, beauty effects and the in-app Library may differ by device, operating system and app version. These Terms do not add features to a version that does not provide them or introduce charges for those features. The app shows the film packs and frames currently available. Missing high-resolution assets download only when you select them or choose to download them; purchasing Pro or refreshing your access does not download every asset. Hiding a film pack does not delete exported photos or downloaded files, or revoke valid Pro access.

2. Your epolar account and Pro access

You may choose to register or sign in using a verification code sent to a mainland China mobile number (+86) or an email address that you lawfully control. Each sign-in identifier can belong to only one account. We reject attempts to link an identifier already used by another account; accounts are not merged automatically. To add another sign-in method, sign in to your existing account first. You cannot currently replace a linked identifier or transfer purchases between accounts yourself. Contact support if you need help. Do not share verification codes or session credentials.

In versions that support epolar accounts, valid Pro access verified by our server can be used with the same epolar account on iOS/iPadOS, Android and HarmonyOS. Signing in does not turn a platform-specific or promotional trial into paid access across all platforms. Older versions without account support continue to use their existing purchase and restore options.

epolar Pro is currently a one-time purchase, not a subscription, and does not renew automatically. The product price, currency, amount due and purchase details are shown on the purchase screen and the payment confirmation screen. Reading these Terms does not incur a charge. Pro access requires periodic online verification. In current versions, access normally refreshes every six hours and remains available offline for up to 24 hours after the last successful verification; the server supplies the applicable intervals. Failed requests do not extend cached access. When the cache expires, verification is required again. This does not mean your one-time purchase has expired or that you need to pay again.

The app explains the scope, dates and eligibility conditions of free-access promotions. These promotions are not purchases and do not renew automatically. Signature cloud sync is not included in free-access promotions. If a purchase is refunded, revoked or found to be invalid, only access granted by that purchase is removed after verification. Other independent, valid sources of access remain unaffected.

3. iOS/iPadOS: Apple purchases and restoration

On iOS/iPadOS, Pro is offered as a non-consumable Apple In-App Purchase. You do not need an epolar account to purchase, restore purchases or use Pro as a guest. Apple handles your Apple Account and payment. epolar does not request your Apple Account password, bank card information or Apple Account email address. Access is granted after our server verifies a valid transaction.

A guest purchase is not automatically linked to an epolar account you later sign in to. To share access through your epolar account, you must explicitly confirm that you want to link the valid purchase to that account. When you start a purchase while signed in, we first ask you to confirm the account it will belong to. A payment that completes later is not reassigned to an account you switch to in the meantime. Each purchase can be linked to only one epolar account and cannot be transferred to another account yourself. Once linked, changing your App Store account does not remove that account's Pro access. To restore an unlinked purchase, use the Apple Account that originally made it.

You can request a refund for an Apple purchase through Apple's refund service, subject to Apple's transaction rules and applicable law. Deleting your epolar account does not automatically refund a purchase. A valid Apple purchase may still be restored for guest use on iOS under Apple's rules, but account deletion does not allow it to be reassigned to another epolar account.

4. Android: purchases and account access

Android versions with purchasing enabled allow you to sign in to epolar and buy Pro through an available Alipay or WeChat Pay option. Available payment methods, prices and purchase availability are shown in your app version and the payment provider's checkout. If your account already has valid Pro access, you can sign in and verify that access in Android versions that support accounts.

Before you pay, the purchase screen explains the payment provider, price, included access and the account the purchase will belong to. Check your signed-in epolar account and the checkout amount. A new Android purchase belongs to the epolar account signed in when the order was created. Cancelling a payment does not grant Pro, and a success message from the app alone is not enough: our server must validate the payment signature and verify the order with the provider. Refunds are handled under the selected provider's rules and applicable law. You can also contact support@epolar.cn for help.

5. HarmonyOS: purchases and account access

HarmonyOS versions with purchasing enabled allow you to sign in to epolar and buy Pro through an available Alipay or WeChat Pay option. Confirm the price on the purchase screen and the selected provider's checkout. Existing, valid account-based Pro access can also be verified after sign-in on supported HarmonyOS versions. Free features do not require sign-in. Account-based promotions, account access and signature cloud sync require sign-in where specified by the feature.

A purchase belongs to the epolar account signed in when the order was created. Your payment account and epolar account are managed separately: changing payment accounts or devices does not transfer the purchase to another epolar account. Cancelling does not grant access. After payment, our server must validate the payment signature and verify the order with the selected provider before granting the corresponding access. Refunds are handled under that provider's rules and applicable law. You can also contact support@epolar.cn for help.

6. Support the Developer

Versions that offer Support the Developer let you choose a preset or custom amount to help maintain epolar. No epolar account is required. Each payment is voluntary, initiated by you and confirmed at checkout. You may support the developer more than once; there is no subscription or automatic renewal. Choosing not to pay does not affect free features or valid access you already have. A support payment does not purchase, unlock or extend epolar Pro, film packs, signatures or other digital content. It is separate from a Pro purchase and is not a charitable donation or charitable fundraising payment.

Check the payment method, amount and receiving merchant shown on the support screen and at checkout before confirming. The current payment options are Alipay and WeChat Pay, where enabled for the platform and app version. Pro purchases on iOS/iPadOS continue to use Apple In-App Purchase. Our server verifies payment signatures and checks payment status with the provider. An app callback reporting success, cancellation or a network interruption does not by itself establish whether payment was received. If the result is pending, you can continue the existing order or check that payment's status. This is not a payment-history feature. Once payment is confirmed, a thank-you message appears. Dismissing it does not prevent you from supporting the developer again.

Support orders are separate from your epolar account and Pro records. There is currently no support-payment history or cross-device restoration of support records. Signing out or deleting your epolar account does not automatically refund support payments or delete records we must retain by law. For mistaken or duplicate payments, payments by minors without required consent, or other disputes, contact support@epolar.cn with the necessary transaction number, date and amount. Do not send payment passwords or verification codes. We will investigate and handle the request under the payment provider's rules and applicable law, without excluding your statutory refund or other remedies. Refunding a support payment does not affect Pro purchased separately.

7. Photos, signatures and cloud sync

Photos, videos, composition adjustments and image rendering are processed on your device. epolar does not provide cloud photo backup. You retain the rights you hold in photos and handwriting you lawfully provide, and you must have the right to use that content. The app, film frames and bundled assets belong to their respective rights holders. Using the editor does not grant a separate license to third-party trademarks or works. You must not extract bundled assets and redistribute or sell them as an asset pack.

Signatures are for photo editing and decoration. They are not an electronic signing, identity verification or legal authorization service. Signatures stay on your device by default. Selected signatures sync only after you sign in with a verified phone number or email address, have valid account-based Pro access and explicitly enable cloud sync. Signing in, purchasing or opening the signature library does not automatically upload local signatures that do not belong to an account. You must explicitly choose to add those signatures to the current account.

Signature libraries are separate for each account and platform: iOS/iPadOS share one library, Android has another and HarmonyOS has another. These three libraries do not currently sync with each other. Sharing Pro access across platforms does not sync signatures, photos or finished images across platforms. Enabling sync for the first time or choosing Sync Now retrieves changes for the current account. While sync is enabled, edits are saved locally before being submitted in the background. A network failure does not mean a change reached the cloud. Turning sync off does not delete existing copies. Deleting a local signature while sync is off does not delete its cloud copy. To delete a cloud signature, complete the deletion with sync enabled or contact support.

Versions with an in-app Library use a local index to show photos saved by epolar. The Library is not a separate photo backup. Sharing uses the system share sheet to send selected content to the recipient you choose. Deleting asks the system to remove the corresponding photos; cancelling system confirmation leaves them unchanged. Recovery depends on the system photo library's capabilities. Save important work before uninstalling the app, clearing its data or changing devices.

8. Film Frame Workshop

The website's Film Frame Workshop lets invited creators adjust artwork, preview frames and export asset packs locally in a browser. An invitation code provides workshop access only; it does not purchase Pro, grant rights to artwork or promise publication. Importing, previewing or exporting does not automatically upload your work, publish it in the app or transfer your copyright. You must have the right to use the images and other content you provide. Any separate submission, licensing or publication of your work will be handled under arrangements agreed with you.

9. Signing out, deleting your account and managing data

Account settings provide sign-out and account-deletion options. Sensitive actions, such as linking a sign-in method or deleting your account, may require recent verification. Signing out revokes the current session and hides that account's signatures; they become available again when you sign back in to the same account. Account deletion removes your phone number, email address, account details, sessions and cloud signatures from the live application database. Necessary order, access, de-identified purchase-linking and refund records are retained only as needed for the relevant obligations. Purchases are not automatically transferred or reassigned.

Account deletion does not delete photos in your system photo library or local signatures that do not belong to the account, and it does not request a refund. Signatures belonging to a deleted account are no longer accessible through that account. Anonymous feedback is not automatically removed when an account is deleted; account-linked feedback is removed with the account. See the epolar Privacy Policy for the data involved, retention, platform permissions and your privacy rights.

10. Minors, service maintenance, changes and disputes

Minors should use epolar with a parent or guardian's guidance. Where parental or guardian consent is required for a purchase or personal information processing, it must be obtained first. Children under 14 should not submit a phone number, email address or feedback containing personal information on their own. Parents and guardians can contact support to have such matters checked and addressed.

We take reasonable steps to maintain the service, provide appropriate notice of necessary maintenance, suspension or closure, and handle valid access in accordance with the law. Your device, network, system services and available storage may affect previewing, saving and verification. We remain responsible as required by law for issues attributable to us. These Terms do not exclude liability that cannot lawfully be excluded or limit your statutory rights.

Updates to these Terms will show a date and version. We will notify you through the app or another appropriate means of changes materially affecting your rights. Where consent or renewed consent is required by law, we will obtain it before the relevant processing; continued use is not a substitute for an explicit choice.

These Terms are governed by the laws of mainland China. You may first contact support@epolar.cn to try to resolve a dispute. If it cannot be resolved, either party may bring proceedings before a court with jurisdiction under applicable law. This does not limit your statutory rights to complain, seek a refund, claim compensation or pursue other remedies. Any mandatory consumer protections that apply where you live remain unaffected.
